Summary : The Berkeley Internet Name Domain (BIND) DNS (Domain Name System) server
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.

cause your server to become part of large scale DNS amplification

reduce such attack surface
