BIND

A name server for the BSD operating system; a network service that enables clients to name resources or objects and share this information with other objects in the network. Put simply, it is a distributed database system for objects in a computer network. BIND is fully integrated into BSD network programs for use in storing and retrieving host names and DNS address. The system administrator can configure the system to use BIND as a replacement for the older host table lookup; the default configuration for BSD uses BIND.
