DOMAIN NAME SERVICE (DNS)

Sometimes referred to as the BIND service in BSD UNIX; a static, hierarchical name service for TCP/IP hosts. A DNS server maintains a database for resolving host names and IP addresses, allowing users of computers configured to query the DNS to specify remote computers by host names rather than IP addresses. DNS domains should not be confused with Windows NT networking domains.
For example, issuing the "ping ftp.microsoft.com" command goes to the DNS server you specified, looks up the IP address for the site, and then pings that IP address.
