Interesting-- was it a multicast address (224.0.0.XXX) and port 5353?  If so, 
that is multicast DNS, or mDNS, used by Zeroconf and Rendezvous mainly on 
Windows and the Mac.

Better living through chemistry.
Life is too short to stay entirely sober.  :-)

Hmph.  Your best bet would have been to point to a remote proxy you know about 
by IP address.  Otherwise, I believe Apple has mDNS code on their Darwin site, 
and a quick look around also suggests:

"mdnsd is a very lightweight, simple, portable, and easy to integrate open
source implementation of Multicast DNS (part of Zeroconf, also called
Rendezvous by Apple) for developers. It supports both acting as a Query and
a Responder, allowing any software to participate fully on the
.localnetwork.
