Every computer connected to the Internet must have a unique address known as an IP (Internet Protocol) address. The IP address is a numeric address written as a set of four numbers separated by dots, for example 64.149.219.213. The address provides a unique identification of a computer and the network it belongs to.

An addressing construct used for identifying and locating computers on the Internet. Domain names provide a system of easy-to-remember Internet addresses, which can be translated by the Domain Name System (DNS) into the numeric addresses (Internet Protocol (IP) numbers) used by a network.
