%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; a resolver library
(routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating properly.

%package utils
Summary: Utilities for querying DNS name servers.
Group: Applications/System

%description utils
Bind-utils contains a collection of utilities for querying DNS (Domain
Name System) name servers to find out information about Internet
hosts. These tools will provide you with the IP addresses for given
host names, as well as other information about registered domains and
network addresses.

You should install bind-utils if you need to get information from DNS name
servers.
