What is an IP address? Internet Protocol address is a unique feature code assigned to a network-connected gadget. Network and node numbers are essential components of IP address. It’s presented by binary numbers of 32 bit in IPv4 version and 128 bit in IPv6. Usually IP addresses consist of four decimal numbers from 0 to 255 separated by dots.

Example of IP address: is a traditional decimal form of address interpretation.

11000000.00111101011 is a binary form of its interpretation.

IP is just a fundamental address’s type on the basis of which IP protocol transmit data packages between networks on the network layer. Address is designated by an administrator during computers and routers configuration.

Address assignment directly depends on network type. If there is an isolated network, its address is chosen by an administrator from specially reserved blocks. But if network is designed to be the Internet component, there are providers or Regional Internet Registry (RIR) who distribute addresses.

Nowadays there are five RIR:

  1. ARIN operates in North America;
  2. APNIC distributes  Southeast Asia region;

  3. African countries are reporting to AfriNIC;
  4. South America and Caribbean countries fall within the scope of LACNIC activity;
  5. RIPE NCC has designed for Europe, Central Asia and Middle East. 

Regional registrars receive autonomous system numbers and address blocks from ICANN (Internet Corporation for Assigned Names and Numbers) and then distribute numbers and off-size blocks to Local Internet Registries (LIR).

Types of IP address

There are two types of addresses: static IP which is a non-removable number assigned to a concrete computer in the network, and dynamic IP given as often as coming online.

As general, static addresses are occupied by corporate bodies. With static IP you can create a proper server and have an access to remote data over known address.

Dynamic IP address can't be detected that is useful for downloading files and visiting needed websites even if your IP has been banned.

Which address is better: static or dynamic?

Static IP addresses are used in locations, such as web-servers, where you don’t need to worry about security problems. Whereas dynamic IP is required for internet browsing, files downloading or e-mail receiving.

In such a manner, IP address is little more than a number of your computer in the network, as well as people location, without which you can’t receive any information about particular person.
