Net::DNS is a Perl interface to the DNS resolver. It allows the

programmer to perform any type of DNS query from a Perl script.
For details and examples, please read the Net::DNS manual page.

As of version 0.02, Net::DNS is written entirely in Perl.  Version
0.01 was written mostly in C and used the system's resolver.  The
Perl version runs quite a bit slower, but considering that the
network can be a serious bottleneck when making DNS queries, the
speed difference may not really matter in most cases.  However,
future versions may contain some C to increase speed or for those
who wish to link against libresolv or libbind.
