Heh, that's such a common misconception that I almost mentioned it in my
original email.  Most DNS queries take place over UDP, however if the
reply to the query is especially large then a new TCP connection is
opened between the client and server.  Also zone transfers take place
over TCP IIRC, it depends what kind of functionality the DNS server will
be providing.
