Stands for Berkeley Internet Name Domain, a popular software tool for administering and maintaining the Domain Name System (DNS) on UNIX platforms. BIND was originally written for BSD UNIX and is currently maintained by the Internet Software Consortium.
Because most versions of UNIX include some port of BIND, it is the most popular DNS server used by Internet service providers (ISPs) for administering and maintaining the DNS for the Internet.
The DNS server services on Microsoft Windows NT and Windows 2000 are RFC-compliant implementations of DNS and are compatible with BIND.
