« Back to Domain Name Dictionary | Definition of Name Server
On the Internet, a name server (also spelled nameserver) consists of a program or computer server that implements a name-service protocol. It maps a human-recognizable identifier (such as “domainsherpa.com” to a system-internal, often numeric, identification or addressing component (such as “127.21.5.2”).
The most prominent types of name servers in operation today are the name servers of 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 humanly memorable domain names and hostnames into the corresponding numeric Internet Protocol (IP) addresses, the second principal Internet name space, used to identify and locate computer systems and resources on the Internet.
