Any device connected to the IP network must have a unique IP address within the network. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify an entity.\nDotted Decimals\nThe traditional IP Address (known as IPv4) uses a 32-bit number to represent an IP address, and it defines both network and host address. A 32-bit number is capable of providing roughly 4 billion unique numbers, and hence IPv4 addresses running out as more devices are connected to the IP network. A new version of the\nIP protocol (IPv6)\nhas been invented to offer a virtually limitless number of unique addresses. An IP address is written in \"dotted decimal\" notation, which is 4 sets of numbers separated by period each set representing an 8-bit number ranging from (0-255). An example of an IPv4 address is 216.3.128.12, which is the IP address previously assigned to iplocation.net.\nAn IPv4 address is divided into two parts: network and host address. The network address determines how many of the 32 bits are used for the network address and the remaining bits are used for the host address. The host address can be further divided into subnetwork and host number.\nClass A, B, C and CIDR networks\nTraditionally IP network is classified as an A, B, or C network. The computers identify the class by the first 3 bits (A=000, B=100, C=110), while humans identify the class by the first octet(8-bit) number.

The devices that need to be publicly identified, such as web or mail servers, must have a globally unique IP address; and they are assigned a public IP address. The devices that do not require public access may be assigned a private IP address and make it uniquely identifiable within one organization. For example, a network printer may be assigned a private IP address to prevent the rest of the world from printing from it. To allow organizations to freely assign private IP addresses, the NIC has reserved certain address blocks for private use. A private network is a network that uses\nRFC 1918\nIP address space. The following IP blocks are reserved for private IP addresses.\nClass\nStarting IP Address\nEnding IP Address\nA\n10.0.0.0\n10.255.255.255\nB\n172.16.0.0\n172.31.255.255\nC\n192.168.0.0\n192.168.255.255\nIn addition to the above classful private addresses, 169.254.0.0 through 169.254.255.255 addresses are reserved for Zeroconf (or APIPA, Automatic Private IP Addressing) to automatically create the usable IP network without configuration.\nWhat is a loopback IP address?\nThe loopback IP address is the address used to access itself. The IPv4 designated\n127.0.0.1\nas the loopback address with the 255.0.0.0\nsubnet mask\n. A loopback interface is also known as a virtual IP, which does not associate with a hardware interface. On Linux systems, the loopback interface is commonly called\nlo\nor\nlo0\n. The corresponding hostname for this interface is called\nlocalhost\n.\nThe loopback address is used to test network software without physically installing a\nN\network\nI\nnterface\nC\nard (NIC), and without having to physically connect the machine to a TCP\/IP network. A good example of this is to access the web server running on itself by using http:\/\/127.0.0.1 or http:\/\/localhost.","attrs_markdown":"[![IP Location Logo](https:\/\/www.iplocation.net\/assets\/images\/logo.png)](https:\/\/www.iplocation.net\/)\n\n[![IP Location Logo](https:\/\/www.iplocation.net\/assets\/images\/logo.png)](https:\/\/www.iplocation.net\/)\n\n[≡ Menu](https:\/\/www.iplocation.net\/what-is-my-ip-address)\n\n- [Trace Email](https:\/\/www.iplocation.net\/go\/trace-email\/mega-menu)\n- [Verify Email](https:\/\/tools.iplocation.net\/verify-email-address)\n- [Contact Us](https:\/\/www.iplocation.net\/contact-us)\n- [Sign In]()\n\n×\n\n- [My IP](https:\/\/www.iplocation.net\/myip)\n  - [What is my IP?](https:\/\/www.iplocation.net\/what-is-my-ip-address)\n  - [Hide IP Address](https:\/\/www.iplocation.net\/hide-ip-address)\n  - [Change IP Address](https:\/\/www.iplocation.net\/change-ip-address)\n- [IP Tracker](https:\/\/tracker.iplocation.net\/)\n- [Tools](https:\/\/tools.iplocation.net\/)\n  - [Online Tools](https:\/\/tools.iplocation.net\/)\n  - [Online Apps](https:\/\/apps.iplocation.net\/)\n- [Web](https:\/\/www.iplocation.net\/world-wide-web)\n  - [Create a Website](https:\/\/www.iplocation.net\/create-website)\n  - [Domain Names](https:\/\/www.iplocation.net\/domain-names)\n  - [Web Hosting](https:\/\/www.iplocation.net\/web-hosting)\n  - [Web Design](https:\/\/www.iplocation.net\/web-design)\n  - [Web Development](https:\/\/developer.iplocation.net\/)\n  - [Web Marketing](https:\/\/www.iplocation.net\/web-marketing)\n  - [Make Money](https:\/\/www.iplocation.net\/make-money)\n- [Privacy](https:\/\/www.iplocation.net\/privacy)\n  - [VPN Comparison](https:\/\/www.iplocation.net\/vpn-comparison)\n  - [Best Proxy Providers](https:\/\/www.iplocation.net\/best-proxy-providers)\n  - [Public Proxy List](https:\/\/www.iplocation.net\/proxy-list)\n  - [Public Data](https:\/\/data.iplocation.net\/)\n  - [Remove my Personal Data](https:\/\/www.iplocation.net\/how-to-remove-my-personal-data-from-the-internet)\n  - [Privacy Scan](https:\/\/www.iplocation.net\/go\/privacy-scan\/tab-menu)\n- [Cybersecurity](https:\/\/www.iplocation.net\/cybersecurity)\n  - [DDoS](https:\/\/www.iplocation.net\/ddos)\n  - [Passwords](https:\/\/www.iplocation.net\/password)\n  - [Online Scams](https:\/\/www.iplocation.net\/scams)\n  - [Email Security](https:\/\/www.iplocation.net\/emails)\n  - [Data Breach Check](https:\/\/www.iplocation.net\/go\/data-breach-check\/tab-menu)\n- [API](https:\/\/api.iplocation.net\/)\n- [Games](https:\/\/www.iplocation.net\/games)\n- [Reviews](https:\/\/www.iplocation.net\/reviews)\n  - [Top 10 Reviews](https:\/\/www.iplocation.net\/top-10-reviews)\n  - [Product Reviews](https:\/\/www.iplocation.net\/reviews)\n- [Learn](https:\/\/www.iplocation.net\/what-is-my-ip-address)\n  - [Tutorials](https:\/\/www.iplocation.net\/tutorials)\n  - [Quizzes](https:\/\/www.iplocation.net\/quizzes)\n- [Blog](https:\/\/www.iplocation.net\/blog)\n  - [Blog Articles](https:\/\/www.iplocation.net\/blog)\n  - [Press Releases](https:\/\/www.iplocation.net\/press-releases)\n\n# What is My IP Address?\n![IP Location Finder](https:\/\/www.iplocation.net\/assets\/images\/tools\/IP1.gif)\n\nYour IP Address is   \n 51\\.161.65.53.  \n  [Hide IP with VPN](https:\/\/www.iplocation.net\/go\/hide-ip-with-vpn\/find-ip-top-link)\n\nThis is the public [IP address](https:\/\/www.iplocation.net\/ip-address) of your computer.

The corresponding hostname for this interface is called localhost . The loopback address is used to test network software without physically installing a N etwork I nterface C ard (NIC), and without having to physically connect the machine to a TCP/IP network. A good example of this is to access the web server running on itself by using http://127.0.0.1 or http://localhost.

The **I**nternet **P**rotocol Address (or IP Address) is a unique address that computing devices such as personal computers, tablets, and smartphones use to identify themselves and communicate with other devices in the IP network. Any device connected to the IP network must have a unique IP address within the network. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify an entity. ### Dotted Decimals The traditional IP Address (known as IPv4) uses a 32-bit number to represent an IP address, and it defines both network and host address. A 32-bit number is capable of providing roughly 4 billion unique numbers, and hence IPv4 addresses running out as more devices are connected to the IP network. A new version of the [IP protocol (IPv6)](https://www.iplocation.net/ipv6-address) has been invented to offer a virtually limitless number of unique addresses. An IP address is written in "dotted decimal" notation, which is 4 sets of numbers separated by period each set representing an 8-bit number ranging from (0-255). An example of an IPv4 address is 216.3.128.12, which is the IP address previously assigned to iplocation.net. An IPv4 address is divided into two parts: network and host address. The network address determines how many of the 32 bits are used for the network address and the remaining bits are used for the host address. The host address can be further divided into subnetwork and host number. ### Class A, B, C and CIDR networks Traditionally IP network is classified as an A, B, or C network. The computers identify the class by the first 3 bits (A=000, B=100, C=110), while humans identify the class by the first octet(8-bit) number. With the scarcity of IP addresses, the class-based system has been replaced by **C**lassless **I**nter-**D**omain **R**outing (CIDR) to more efficiently allocate IP addresses. | Class | Network Address | Number of Hosts | Netmask | |---|---|---|---| | CIDR | /4 | 240,435,456 | 240\.0.0.0 | | CIDR | /5 | 134,217,728 | 248\.0.0.0 | | CIDR | /6 | 67,108,864 | 252\.0.0.0 | | CIDR | /7 | 33,554,432 | 254\.0.0.0 | | A | /8 (1-126) | 16,777,216 | 255\.0.0.0 | | CIDR | /9 | 8,388,608 | 255\.128.0.0 | | CIDR | /10 | 4,194,304 | 255\.192.0.0 | | CIDR | /11 | 2,097,152 | 255\.224.0.0 | | CIDR | /12 | 1,048,576 | 255\.240.0.0 | | CIDR | /13 | 524,288 | 255\.248.0.0 | | CIDR | /14 | 262,144 | 255\.252.0.0 | | CIDR | /15 | 131,072 | 255\.254.0.0 | | B | /16 (128-191) | 65,534 | 255\.255.0.0 | | CIDR | /17 | 32,768 | 255\.255.128.0 | | CIDR | /18 | 16,384 | 255\.255.192.0 | | CIDR | /19 | 8,192 | 255\.255.224.0 | | CIDR | /20 | 4,096 | 255\.255.240.0 | | CIDR | /21 | 2,048 | 255\.255.248.0 | | CIDR | /22 | 1,024 | 255\.255.252.0 | | CIDR | /23 | 512 | 255\.255.254.0 | | C | /24 (192-223) | 256 | 255\.255.255.0 | | CIDR | /25 | 128 | 255\.255.255.128 | | CIDR | /26 | 64 | 255\.255.255.192 | | CIDR | /27 | 32 | 255\.255.255.224 | | CIDR | /28 | 16 | 255\.255.255.240 | | CIDR | /29 | 8 | 255\.255.255.248 | | CIDR | /30 | 4 | 255\.255.255.252 | Note: (1) 127 Network Address reserved for loopback test. (2) Class D (224-247, Multicast) and Class E (248-255, Experimental) are not intended to be used in public operation. ### Public and Private IP Addresses In order to maintain uniqueness within a global namespace, the IP addresses are publicly registered with the **N**etwork **I**nformation **C**enter (NIC) to avoid address conflicts. The devices that need to be publicly identified, such as web or mail servers, must have a globally unique IP address; and they are assigned a public IP address. The devices that do not require public access may be assigned a private IP address and make it uniquely identifiable within one organization. For example, a network printer may be assigned a private IP address to prevent the rest of the world from printing from it. To allow organizations to freely assign private IP addresses, the NIC has reserved certain address blocks for private use. A private network is a network that uses [RFC 1918](http://tools.ietf.org/html/rfc1918) IP address space. The following IP blocks are reserved for private IP addresses. | Class | Starting IP Address | Ending IP Address | |---|---|---| | A | 10\.0.0.0 | 10\.255.255.255 | | B | 172\.16.0.0 | 172\.31.255.255 | | C | 192\.168.0.0 | 192\.168.255.255 | In addition to the above classful private addresses, 169.254.0.0 through 169.254.255.255 addresses are reserved for Zeroconf (or APIPA, Automatic Private IP Addressing) to automatically create the usable IP network without configuration. ### What is a loopback IP address? The loopback IP address is the address used to access itself. The IPv4 designated **127\.0.0.1** as the loopback address with the 255.0.0.0 [subnet mask](https://www.iplocation.net/subnet-mask). A loopback interface is also known as a virtual IP, which does not associate with a hardware interface. On Linux systems, the loopback interface is commonly called **lo** or **lo0**. The corresponding hostname for this interface is called **localhost**. The loopback address is used to test network software without physically installing a **N**etwork **I**nterface **C**ard (NIC), and without having to physically connect the machine to a TCP/IP network. A good example of this is to access the web server running on itself by using http://127.0.0.1 or http://localhost.
