Description:

BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(Domain Name System) protocols. BIND includes a DNS server (named),
which resolves host names to IP addresses, and a resolver library
(routines for applications to use when interfacing with DNS). A DNS
server allows clients to name resources or objects and share the
information with other network machines. The named DNS server can be
used on workstations as a caching name server, but is generally only
needed on one machine for an entire network. Note that the
configuration files for making BIND act as a simple caching nameserver
are included in the caching-nameserver package.

Install the bind package if you need a DNS server for your network. If
you want bind to act a caching name server, you will also need to install
the caching-nameserver package.
