A name server is a computer server that hosts a network service for providing responses to queries against a directory service.

A name server is a computer server that hosts a network service for providing responses to queries against a directory service. It maps a human-recognizable identifier to a system-internal, often numeric, identification or addressing component. This service is performed by the server according to a network service protocol.

Examples of name servers is the Domain Name System (DNS), one of the two principal name spaces of the Internet. The most important function of these DNS servers is the translation (resolution) of human-memorable domain names and hostnames into the corresponding numeric Internet Protocol (IP) addresses, the second principal Internet name space which is used to identify and locate computer systems and resources on the Internet.
