Domain Name System

The Domain Name System (DNS) is a hierarchical, distributed database that contains mappings of DNS domain names to various types of data, such as Internet Protocol (IP) addresses. DNS allows you to use friendly names, such as www.microsoft.com, to easily locate computers and other resources on a TCP/IP-based network. DNS is an Internet Engineering Task Force (IETF) standard.
