| Boilerpipe Text | IP address definition
An IP address is a unique identifier assigned to a device on the internet or a local network. Short for "Internet Protocol," IP refers to the rules that dictate how data is formatted and transmitted across networks.
IP addresses are essential for the internetâs functionality, facilitating communication by directing data between devices, and ensuring it reaches the intended destination. Each IP address includes location details that make devices identifiable within a network, allowing the internet to differentiate between computers, routers, and websites.
The definition of IP address.
How do IP addresses work?
IP addresses work by providing a unique label to each device on a network, allowing them to send and receive data packets according to
TCP/IP
protocols.
Routers
and other network devices use these addresses to route packets to their correct destination, ensuring efficient and accurate communication between devices.
Hereâs a closer look at how IP addresses help facilitate network data transfers:
Device initialization:
Your device connects to a network and prepares to communicate.
IP address assignment:
The network router assigns separate IP addresses to each network device, after receiving its own IP address allocation from an organization like ICANN (Internet Corporation for Assigned Names and Numbers) via the
ISP
(internet service provider).
Domain Name System (DNS) resolution:
When you enter a domain name (like google.com), the
DNS
translates it into a machine-readable IP address. This process allows your device to locate and communicate with the correct server on the internet.
Data packet transmission:
Data is broken into packets, each containing the source and destination IP addresses. These data packets are then sent by the transmitting device and forwarded across the network.
Network address translation (NAT):
NAT modifies IP address information in packet headers as data passes through a router, replacing the private IP address with the routerâs public IP address. This allows multiple devices on a private network to share a single public IP.
Routing and switching:
Routing uses IP addresses to direct data packets between different networks, while switching handles traffic within a single network, using MAC addresses to route packets to specific devices.
Delivery and response:
Data packets arrive at the destination device or server, identified by its IP address. The destination may send a response or acknowledgment back to the source device, using IP addresses to ensure the correct return path.
Renewal and reassignment:
Dynamic IP addresses are periodically renewed and reassigned as devices connect and disconnect from networks. This process ensures each device has a valid, unique IP address, preventing conflicts and maintaining efficient network organization.
Types of IP addresses
Different types of IP addresses are used to manage the limited pool of available addresses, improve security, and meet specific networking needs. These include IPv4 and IPv6 IP addresses, public and private IP addresses, and static and dynamic IP addresses.
A comparison of different types of IP addresses.
IPv4
IPv4 is a legacy generation of IP thatâs still widely used. They use a 32-bit address format, represented in dotted decimal notation, with a maximum of 15 characters. Its main drawback is limited address space, with only around 4 billion possible unique addresses. To help cope with address exhaustion, ISPs use techniques like NAT, enabling multiple devices to share a single public IP.
An example of an IPv4 address is:
192.168.1.1
.
IPv6
IPv6 addresses are the newest IP address iteration. These types of IPs offer a greatly expanded address space, by using 128-bit addresses written as eight groups of four hexadecimal digits. This allows for more than 340 undecillion unique addresses â a limit weâll likely never hit. IPv6 also improves routing efficiency and network security by incorporating
IPsec
authentication and encryption protocols.
An example of an IPv6 address is:
2401:0fc8:85b3:0000:0000:8b6e:0730:7314
.
Public IP address
A public IP address is assigned to devices like routers, which are directly accessible over the internet. Public IPs are globally unique and traceable, which allows external devices to communicate with your network â but it also makes them visible and traceable to a specific location. To enhance privacy and security, devices within a local network typically share one public IP address.
Private IP address
A
private IP address
, or local IP address, is assigned by your router to devices within your local network. Each device gets a unique private IP to help the router direct traffic correctly. Unlike
public IP addresses
, which are visible on the internet, private IPs remain confined to your local network, which means they donât need to be universally unique and can be reused across multiple networks.
Static IP address
Static IP addresses, also known as dedicated or fixed IP addresses, donât change. Once a device is assigned an IP address, that address remains the same. Static IP addresses are common for web servers, email servers, or other devices that need to be consistently accessible at the same address.
Dynamic IP address
Dynamic IP addresses are temporary addresses assigned to devices by a networkâs DHCP server each time a device connects to the network. This allows efficient use of available addresses, making it ideal for networks with many users. Dynamic IPs also offer security benefits, since their changing nature makes it harder for hackers to target.
How to find your IP address
You can find your public IP address by Googling âWhat is my IP?â Google and other web services know your IP address because itâs assigned to your device and is required to connect to the internet in the first place. When you search, Google usually displays your public IP address in an info box, but you might need to scroll down a bit to see it.
An example of where you can find your IP address on Google.
But if you want to see your computer or phoneâs network-provided IP address â known as your private IP address â youâll need to look up the local IP directly on your device.
Find your IP address on Windows
Hereâs how to look up your IP address on a PC:
Go to
Start
>
Settings
>
Network & internet
.
Select
Wi-Fi
(for wireless connections) or
Ethernet
(for wired connections).

What can someone do with your IP address?
If
someone has your IP address
, they can approximate your location, track your online activity, and potentially target you with ads or cyber attacks. While an IP alone wonât typically lead to hacking, it can be a starting point for identifying and exploiting vulnerabilities in your network.
Hereâs a closer look at ways a cybercriminal may use your IP address:
Monitor your online activity:
A criminal could monitor your online activity using your IP address by intercepting network traffic or exploiting vulnerabilities to access your devices or data.
Launch cyberattacks:
Your IP address could be used to launch attacks like
DDoS attacks
, overwhelming your network with traffic to disrupt your connection. They may also target you with
spyware
or
malware
, potentially gaining access to your device and personal data.
Personalize spam and scams:
Cybercriminals can use your IP address to find your general location. Later, they can leverage this information to personalize scams and
spam messages
, making them seem more relevant to you.
Impersonate you:
If a hacker has your IP address, they could attempt to impersonate you by
spoofing your IP
to make it seem like their activity originates from your device.
How to hide your IP address
Common methods for
hiding an IP address
include using a VPN, proxy server, NAT firewall, or anonymizing browser. You can also try connecting to a non-static IP address or resetting your router.
Hereâs a closer look at different ways to hide your IP address:
VPNs:
A
VPN
hides your IP address by encrypting and routing your internet traffic through a VPN server, which assigns you a new IP address and masks your original one.
Proxy servers:
Although they typically lack encryption,
proxies
can help hide your IP address by displaying their server IP address to the sites you visit.
Dynamic IP addresses:
Your IP address wonât exactly be obscured, but by changing periodically, dynamic IP addresses assigned by a
public Wi-Fi network
or your mobile carrier make it harder for you to be tracked or targeted.
NAT firewalls:
A NAT
firewall
on your router helps hide your IP address by using a shared public IP for multiple devices, preventing incoming traffic from accessing your devices directly without
port forwarding
.
Reset your modem:
Resetting your modem can assign a new dynamic IP address, replacing your previous IP and disrupting any ongoing tracking or attacks aimed at your old IP address.
Browse with Tor:
By routing your internet traffic through an encrypted network of server ânodes,âÂ
Tor
helps mask your original IP address â although it is still exposed to the first node in the network.
Reset your router:
Performing a router reset may assign a new local IP to devices, but it wonât necessarily change your public IP unless your ISP provides a dynamic IP.
Mask your IP address
Donât want hackers turning up on your digital doorstep? Hiding your IP address with a VPN from a trusted brand is the most effective and reliable way to boost your internet privacy and security.
Norton VPN
helps shield your IP address from prying eyes looking to track your online activity, uncover your location, or steal sensitive personal or financial data. Thanks to bank-grade encryption, your IP is masked, and your data is routed through a secure tunnel, helping to ensure a private and secure online experience every time you connect.
FAQs
Can I change my IP address?
Yes, you can
change your IP address
. An easy and secure way to do so is to use a VPN to assign your device a virtual IP address whenever you connect, keeping your real IP address private.
What's the difference between a MAC address and IP address?
A Media Access Control (MAC) address is a permanent and unique hardware identifier for a deviceâs network interface controller (NIC), used for communication within a local network. In contrast, an IP address identifies a deviceâs connection to a network and can change depending on location and connection type.
Does your IP address change with location?
Yes, an IP address can change with location. When you connect to the internet from different places, such as different Wi-Fi networks or using mobile data, your device is assigned a new IP address based on the network's location. This helps identify your approximate geographical location.
What is a loopback IP address?
A loopback IP address routes data packets from the original device back to itself so it doesnât travel over the internet. Developers and network administrators typically use loopback IPs to perform tests or debugging.
What is the 192.168 IP address?
192.168.x.x is a private default address commonly used for routers in home networks and other small private networks. Each device connected to the same local network shares the same number sequence at the beginning but has a unique identifier at the end. |

An IP address is a unique identifier assigned to a device on the internet or a local network. Short for "Internet Protocol," IP refers to the rules that dictate how data is formatted and transmitted across networks.
IP addresses are essential for the internetâs functionality, facilitating communication by directing data between devices, and ensuring it reaches the intended destination. Each IP address includes location details that make devices identifiable within a network, allowing the internet to differentiate between computers, routers, and websites.


The definition of IP address.
## How do IP addresses work?
IP addresses work by providing a unique label to each device on a network, allowing them to send and receive data packets according to [TCP/IP](https://us.norton.com/blog/privacy/tcp-ip) protocols. [Routers](https://us.norton.com/blog/iot/smarter-home-what-is-router) and other network devices use these addresses to route packets to their correct destination, ensuring efficient and accurate communication between devices.
Hereâs a closer look at how IP addresses help facilitate network data transfers:
1. **Device initialization:** Your device connects to a network and prepares to communicate.
2. **IP address assignment:** The network router assigns separate IP addresses to each network device, after receiving its own IP address allocation from an organization like ICANN (Internet Corporation for Assigned Names and Numbers) via the [ISP](https://us.norton.com/blog/wifi/what-is-an-isp) (internet service provider).
3. **Domain Name System (DNS) resolution:** When you enter a domain name (like google.com), the [DNS](https://us.norton.com/blog/how-to/what-is-my-dns) translates it into a machine-readable IP address. This process allows your device to locate and communicate with the correct server on the internet.
4. **Data packet transmission:** Data is broken into packets, each containing the source and destination IP addresses. These data packets are then sent by the transmitting device and forwarded across the network.
5. **Network address translation (NAT):** NAT modifies IP address information in packet headers as data passes through a router, replacing the private IP address with the routerâs public IP address. This allows multiple devices on a private network to share a single public IP.
6. **Routing and switching:** Routing uses IP addresses to direct data packets between different networks, while switching handles traffic within a single network, using MAC addresses to route packets to specific devices.
7. **Delivery and response:** Data packets arrive at the destination device or server, identified by its IP address. The destination may send a response or acknowledgment back to the source device, using IP addresses to ensure the correct return path.
8. **Renewal and reassignment:** Dynamic IP addresses are periodically renewed and reassigned as devices connect and disconnect from networks. This process ensures each device has a valid, unique IP address, preventing conflicts and maintaining efficient network organization.
## Types of IP addresses
Different types of IP addresses are used to manage the limited pool of available addresses, improve security, and meet specific networking needs. These include IPv4 and IPv6 IP addresses, public and private IP addresses, and static and dynamic IP addresses.


A comparison of different types of IP addresses.
### IPv4
IPv4 is a legacy generation of IP thatâs still widely used. They use a 32-bit address format, represented in dotted decimal notation, with a maximum of 15 characters. Its main drawback is limited address space, with only around 4 billion possible unique addresses. To help cope with address exhaustion, ISPs use techniques like NAT, enabling multiple devices to share a single public IP.
An example of an IPv4 address is: **192\.168.1.1**.
### IPv6
IPv6 addresses are the newest IP address iteration. These types of IPs offer a greatly expanded address space, by using 128-bit addresses written as eight groups of four hexadecimal digits. This allows for more than 340 undecillion unique addresses â a limit weâll likely never hit. IPv6 also improves routing efficiency and network security by incorporating [IPsec](https://us.norton.com/blog/privacy/what-is-ipsec) authentication and encryption protocols.
An example of an IPv6 address is: **2401:0fc8:85b3:0000:0000:8b6e:0730:7314**.
### Public IP address
A public IP address is assigned to devices like routers, which are directly accessible over the internet. Public IPs are globally unique and traceable, which allows external devices to communicate with your network â but it also makes them visible and traceable to a specific location. To enhance privacy and security, devices within a local network typically share one public IP address.
### Private IP address
A [private IP address](https://us.norton.com/blog/privacy/private-ip-address), or local IP address, is assigned by your router to devices within your local network. Each device gets a unique private IP to help the router direct traffic correctly. Unlike [public IP addresses](https://us.norton.com/blog/privacy/public-vs-private-ip-address), which are visible on the internet, private IPs remain confined to your local network, which means they donât need to be universally unique and can be reused across multiple networks.
### Static IP address
Static IP addresses, also known as dedicated or fixed IP addresses, donât change. Once a device is assigned an IP address, that address remains the same. Static IP addresses are common for web servers, email servers, or other devices that need to be consistently accessible at the same address.
### Dynamic IP address
Dynamic IP addresses are temporary addresses assigned to devices by a networkâs DHCP server each time a device connects to the network. This allows efficient use of available addresses, making it ideal for networks with many users. Dynamic IPs also offer security benefits, since their changing nature makes it harder for hackers to target.
## How to find your IP address
You can find your public IP address by Googling âWhat is my IP?â Google and other web services know your IP address because itâs assigned to your device and is required to connect to the internet in the first place. When you search, Google usually displays your public IP address in an info box, but you might need to scroll down a bit to see it.


An example of where you can find your IP address on Google.
But if you want to see your computer or phoneâs network-provided IP address â known as your private IP address â youâll need to look up the local IP directly on your device.
### Find your IP address on Windows
Hereâs how to look up your IP address on a PC:
1. Go to **Start** \> **Settings** \> **Network & internet**.
2. Select **Wi-Fi** (for wireless connections) or **Ethernet** (for wired connections).

## What can someone do with your IP address?
If [someone has your IP address](https://us.norton.com/blog/privacy/what-can-someone-do-with-ip-address), they can approximate your location, track your online activity, and potentially target you with ads or cyber attacks. While an IP alone wonât typically lead to hacking, it can be a starting point for identifying and exploiting vulnerabilities in your network.
Hereâs a closer look at ways a cybercriminal may use your IP address:
- **Monitor your online activity:** A criminal could monitor your online activity using your IP address by intercepting network traffic or exploiting vulnerabilities to access your devices or data.
- **Launch cyberattacks:** Your IP address could be used to launch attacks like [DDoS attacks](https://us.norton.com/blog/emerging-threats/ddos-attacks), overwhelming your network with traffic to disrupt your connection. They may also target you with [spyware](https://us.norton.com/blog/malware/spyware) or [malware](https://us.norton.com/blog/emerging-threats/malware), potentially gaining access to your device and personal data.
- **Personalize spam and scams:** Cybercriminals can use your IP address to find your general location. Later, they can leverage this information to personalize scams and [spam messages](https://us.norton.com/blog/online-scams/what-is-spam), making them seem more relevant to you.
- **Impersonate you:** If a hacker has your IP address, they could attempt to impersonate you by [spoofing your IP](https://us.norton.com/blog/malware/what-is-ip-spoofing) to make it seem like their activity originates from your device.
## How to hide your IP address
Common methods for [hiding an IP address](https://us.norton.com/blog/privacy/how-to-hide-your-ip-address) include using a VPN, proxy server, NAT firewall, or anonymizing browser. You can also try connecting to a non-static IP address or resetting your router.
Hereâs a closer look at different ways to hide your IP address:
- **VPNs:** A [VPN](https://us.norton.com/blog/privacy/what-is-a-vpn) hides your IP address by encrypting and routing your internet traffic through a VPN server, which assigns you a new IP address and masks your original one.
- **Proxy servers:** Although they typically lack encryption, [proxies](https://us.norton.com/blog/privacy/proxy-vs-vpn) can help hide your IP address by displaying their server IP address to the sites you visit.
- **Dynamic IP addresses:** Your IP address wonât exactly be obscured, but by changing periodically, dynamic IP addresses assigned by a [public Wi-Fi network](https://us.norton.com/blog/privacy/public-wifi) or your mobile carrier make it harder for you to be tracked or targeted.
- **NAT firewalls:** A NAT [firewall](https://us.norton.com/blog/privacy/firewall) on your router helps hide your IP address by using a shared public IP for multiple devices, preventing incoming traffic from accessing your devices directly without [port forwarding](https://us.norton.com/blog/how-to/how-to-port-forward).
- **Reset your modem:** Resetting your modem can assign a new dynamic IP address, replacing your previous IP and disrupting any ongoing tracking or attacks aimed at your old IP address.
- **Browse with Tor:** By routing your internet traffic through an encrypted network of server ânodes,â [Tor](https://us.norton.com/blog/vpn/tor-vs-vpn) helps mask your original IP address â although it is still exposed to the first node in the network.
- **Reset your router:** Performing a router reset may assign a new local IP to devices, but it wonât necessarily change your public IP unless your ISP provides a dynamic IP.
## Mask your IP address
Donât want hackers turning up on your digital doorstep? Hiding your IP address with a VPN from a trusted brand is the most effective and reliable way to boost your internet privacy and security.
[Norton VPN](https://us.norton.com/products/norton-vpn) helps shield your IP address from prying eyes looking to track your online activity, uncover your location, or steal sensitive personal or financial data. Thanks to bank-grade encryption, your IP is masked, and your data is routed through a secure tunnel, helping to ensure a private and secure online experience every time you connect.

## FAQs
### Can I change my IP address?
Yes, you can [change your IP address](https://us.norton.com/blog/how-to/change-ip-address). An easy and secure way to do so is to use a VPN to assign your device a virtual IP address whenever you connect, keeping your real IP address private.
### What's the difference between a MAC address and IP address?
A Media Access Control (MAC) address is a permanent and unique hardware identifier for a deviceâs network interface controller (NIC), used for communication within a local network. In contrast, an IP address identifies a deviceâs connection to a network and can change depending on location and connection type.
### Does your IP address change with location?
Yes, an IP address can change with location. When you connect to the internet from different places, such as different Wi-Fi networks or using mobile data, your device is assigned a new IP address based on the network's location. This helps identify your approximate geographical location.
### What is a loopback IP address?
A loopback IP address routes data packets from the original device back to itself so it doesnât travel over the internet. Developers and network administrators typically use loopback IPs to perform tests or debugging.
### What is the 192.168 IP address?
192\.168.x.x is a private default address commonly used for routers in home networks and other small private networks. Each device connected to the same local network shares the same number sequence at the beginning but has a unique identifier at the end.

| Readable Markdown | ## IP address definition
An IP address is a unique identifier assigned to a device on the internet or a local network. Short for "Internet Protocol," IP refers to the rules that dictate how data is formatted and transmitted across networks.
IP addresses are essential for the internetâs functionality, facilitating communication by directing data between devices, and ensuring it reaches the intended destination. Each IP address includes location details that make devices identifiable within a network, allowing the internet to differentiate between computers, routers, and websites.


The definition of IP address.
## How do IP addresses work?
IP addresses work by providing a unique label to each device on a network, allowing them to send and receive data packets according to [TCP/IP](https://us.norton.com/blog/privacy/tcp-ip) protocols. [Routers](https://us.norton.com/blog/iot/smarter-home-what-is-router) and other network devices use these addresses to route packets to their correct destination, ensuring efficient and accurate communication between devices.
Hereâs a closer look at how IP addresses help facilitate network data transfers:
1. **Device initialization:** Your device connects to a network and prepares to communicate.
2. **IP address assignment:** The network router assigns separate IP addresses to each network device, after receiving its own IP address allocation from an organization like ICANN (Internet Corporation for Assigned Names and Numbers) via the [ISP](https://us.norton.com/blog/wifi/what-is-an-isp) (internet service provider).
3. **Domain Name System (DNS) resolution:** When you enter a domain name (like google.com), the [DNS](https://us.norton.com/blog/how-to/what-is-my-dns) translates it into a machine-readable IP address. This process allows your device to locate and communicate with the correct server on the internet.
4. **Data packet transmission:** Data is broken into packets, each containing the source and destination IP addresses. These data packets are then sent by the transmitting device and forwarded across the network.
5. **Network address translation (NAT):** NAT modifies IP address information in packet headers as data passes through a router, replacing the private IP address with the routerâs public IP address. This allows multiple devices on a private network to share a single public IP.
6. **Routing and switching:** Routing uses IP addresses to direct data packets between different networks, while switching handles traffic within a single network, using MAC addresses to route packets to specific devices.
7. **Delivery and response:** Data packets arrive at the destination device or server, identified by its IP address. The destination may send a response or acknowledgment back to the source device, using IP addresses to ensure the correct return path.
8. **Renewal and reassignment:** Dynamic IP addresses are periodically renewed and reassigned as devices connect and disconnect from networks. This process ensures each device has a valid, unique IP address, preventing conflicts and maintaining efficient network organization.
## Types of IP addresses
Different types of IP addresses are used to manage the limited pool of available addresses, improve security, and meet specific networking needs. These include IPv4 and IPv6 IP addresses, public and private IP addresses, and static and dynamic IP addresses.


A comparison of different types of IP addresses.
### IPv4
IPv4 is a legacy generation of IP thatâs still widely used. They use a 32-bit address format, represented in dotted decimal notation, with a maximum of 15 characters. Its main drawback is limited address space, with only around 4 billion possible unique addresses. To help cope with address exhaustion, ISPs use techniques like NAT, enabling multiple devices to share a single public IP.
An example of an IPv4 address is: **192\.168.1.1**.
### IPv6
IPv6 addresses are the newest IP address iteration. These types of IPs offer a greatly expanded address space, by using 128-bit addresses written as eight groups of four hexadecimal digits. This allows for more than 340 undecillion unique addresses â a limit weâll likely never hit. IPv6 also improves routing efficiency and network security by incorporating [IPsec](https://us.norton.com/blog/privacy/what-is-ipsec) authentication and encryption protocols.
An example of an IPv6 address is: **2401:0fc8:85b3:0000:0000:8b6e:0730:7314**.
### Public IP address
A public IP address is assigned to devices like routers, which are directly accessible over the internet. Public IPs are globally unique and traceable, which allows external devices to communicate with your network â but it also makes them visible and traceable to a specific location. To enhance privacy and security, devices within a local network typically share one public IP address.
### Private IP address
A [private IP address](https://us.norton.com/blog/privacy/private-ip-address), or local IP address, is assigned by your router to devices within your local network. Each device gets a unique private IP to help the router direct traffic correctly. Unlike [public IP addresses](https://us.norton.com/blog/privacy/public-vs-private-ip-address), which are visible on the internet, private IPs remain confined to your local network, which means they donât need to be universally unique and can be reused across multiple networks.
### Static IP address
Static IP addresses, also known as dedicated or fixed IP addresses, donât change. Once a device is assigned an IP address, that address remains the same. Static IP addresses are common for web servers, email servers, or other devices that need to be consistently accessible at the same address.
### Dynamic IP address
Dynamic IP addresses are temporary addresses assigned to devices by a networkâs DHCP server each time a device connects to the network. This allows efficient use of available addresses, making it ideal for networks with many users. Dynamic IPs also offer security benefits, since their changing nature makes it harder for hackers to target.
## How to find your IP address
You can find your public IP address by Googling âWhat is my IP?â Google and other web services know your IP address because itâs assigned to your device and is required to connect to the internet in the first place. When you search, Google usually displays your public IP address in an info box, but you might need to scroll down a bit to see it.

## What can someone do with your IP address?
If [someone has your IP address](https://us.norton.com/blog/privacy/what-can-someone-do-with-ip-address), they can approximate your location, track your online activity, and potentially target you with ads or cyber attacks. While an IP alone wonât typically lead to hacking, it can be a starting point for identifying and exploiting vulnerabilities in your network.
Hereâs a closer look at ways a cybercriminal may use your IP address:
- **Monitor your online activity:** A criminal could monitor your online activity using your IP address by intercepting network traffic or exploiting vulnerabilities to access your devices or data.
- **Launch cyberattacks:** Your IP address could be used to launch attacks like [DDoS attacks](https://us.norton.com/blog/emerging-threats/ddos-attacks), overwhelming your network with traffic to disrupt your connection. They may also target you with [spyware](https://us.norton.com/blog/malware/spyware) or [malware](https://us.norton.com/blog/emerging-threats/malware), potentially gaining access to your device and personal data.
- **Personalize spam and scams:** Cybercriminals can use your IP address to find your general location. Later, they can leverage this information to personalize scams and [spam messages](https://us.norton.com/blog/online-scams/what-is-spam), making them seem more relevant to you.
- **Impersonate you:** If a hacker has your IP address, they could attempt to impersonate you by [spoofing your IP](https://us.norton.com/blog/malware/what-is-ip-spoofing) to make it seem like their activity originates from your device.
## How to hide your IP address
Common methods for [hiding an IP address](https://us.norton.com/blog/privacy/how-to-hide-your-ip-address) include using a VPN, proxy server, NAT firewall, or anonymizing browser. You can also try connecting to a non-static IP address or resetting your router.
Hereâs a closer look at different ways to hide your IP address:
- **VPNs:** A [VPN](https://us.norton.com/blog/privacy/what-is-a-vpn) hides your IP address by encrypting and routing your internet traffic through a VPN server, which assigns you a new IP address and masks your original one.
- **Proxy servers:** Although they typically lack encryption, [proxies](https://us.norton.com/blog/privacy/proxy-vs-vpn) can help hide your IP address by displaying their server IP address to the sites you visit.
- **Dynamic IP addresses:** Your IP address wonât exactly be obscured, but by changing periodically, dynamic IP addresses assigned by a [public Wi-Fi network](https://us.norton.com/blog/privacy/public-wifi) or your mobile carrier make it harder for you to be tracked or targeted.
- **NAT firewalls:** A NAT [firewall](https://us.norton.com/blog/privacy/firewall) on your router helps hide your IP address by using a shared public IP for multiple devices, preventing incoming traffic from accessing your devices directly without [port forwarding](https://us.norton.com/blog/how-to/how-to-port-forward).
- **Reset your modem:** Resetting your modem can assign a new dynamic IP address, replacing your previous IP and disrupting any ongoing tracking or attacks aimed at your old IP address.
- **Browse with Tor:** By routing your internet traffic through an encrypted network of server ânodes,â [Tor](https://us.norton.com/blog/vpn/tor-vs-vpn) helps mask your original IP address â although it is still exposed to the first node in the network.
- **Reset your router:** Performing a router reset may assign a new local IP to devices, but it wonât necessarily change your public IP unless your ISP provides a dynamic IP.
## Mask your IP address
Donât want hackers turning up on your digital doorstep? Hiding your IP address with a VPN from a trusted brand is the most effective and reliable way to boost your internet privacy and security.
[Norton VPN](https://us.norton.com/products/norton-vpn) helps shield your IP address from prying eyes looking to track your online activity, uncover your location, or steal sensitive personal or financial data. Thanks to bank-grade encryption, your IP is masked, and your data is routed through a secure tunnel, helping to ensure a private and secure online experience every time you connect.
## FAQs
### Can I change my IP address?
Yes, you can [change your IP address](https://us.norton.com/blog/how-to/change-ip-address). An easy and secure way to do so is to use a VPN to assign your device a virtual IP address whenever you connect, keeping your real IP address private.
### What's the difference between a MAC address and IP address?
A Media Access Control (MAC) address is a permanent and unique hardware identifier for a deviceâs network interface controller (NIC), used for communication within a local network. In contrast, an IP address identifies a deviceâs connection to a network and can change depending on location and connection type.
### Does your IP address change with location?
Yes, an IP address can change with location. When you connect to the internet from different places, such as different Wi-Fi networks or using mobile data, your device is assigned a new IP address based on the network's location. This helps identify your approximate geographical location.
### What is a loopback IP address?
A loopback IP address routes data packets from the original device back to itself so it doesnât travel over the internet. Developers and network administrators typically use loopback IPs to perform tests or debugging.
### What is the 192.168 IP address?
192\.168.x.x is a private default address commonly used for routers in home networks and other small private networks. Each device connected to the same local network shares the same number sequence at the beginning but has a unique identifier at the end. |
