Domain Name Service


Definition: In a Web address (URL), the domain name is the portion just after “http://”. For example, in “”, the domain name is “”. But having these addresses as text is just a convenience. Computers see everything as numbers, including address information (see IP address). The Domain Name Service is simply a two-way translation so that computers can understand the text-based addresses we use, and so that we don’t have to memorize long strings of numbers.
