I wrote a simple DNS client for TCP some time ago, but I'm sure that
seeing the code won't help you. :-)

Oh, and DNS can use both UDP and TCP, so I guess a dns.el should use
both, with the appropriate fallback UDP->TCP.

There was a library posted to gnu.emacs.sources recently for dealing
with binary structures, it might be useful for unpacking DNS packets.
