Does DNS resolve names through UDP? Would that explain why I can't telnet
to port 53 on the DNS servers,yet still get name resolutions? Am I wrong conceptually
on how DNS works?
DNS resolves queries when possible using UDP, and when the query is too large for a UDP packet it can also use TCP. So udp/53 and tcp/53 must both be open in order for DNS to work properly.
