hello, i also made a search on that and i found that it uses UDP.
So i whent to my Ethereal and put it snifing while in browser i typed
www.sdfsd.fgfds.pt (since my browser and OS didn't know it, a query was sent). I can send you the log if you want but you can also check for your self if you get the program.
Have a good work on that
