From what I have read, public DNS servers should support both UDP andTCP queries. TCP queries are often used when a UDP query fails, or if the answer is over a certain length.
UDP is used for queries. TCP is used for zone transfers. If my server responded to TCP queries from anyone other than a secondary server, I would be VERY concerned. Jon Kibler - -- Jon R.
