I think you mean port 53.  This is both TCP and UDP.  I thought DNS
used both TCP and UDP.  Thus firewall that is blocking UDP traffic will
cause zone updates to fail.
name            42/udp          nameserver
whois           43/tcp          nicname         # usually to sri-nic
domain          53/tcp
domain          53/udp


Queries are done via UDP; zone transfers are always fully TCP.
