You're probably not querying it for the correct record. Remember, with
sub /24 delegations done by CNAME your DNS server doesn't have the
reverse records for your IP block, your provider does. Your provider
tells the world that each ``real'' record is an alias for a record in
the zone on your servers.

Tell us what your actual IP block and server IP is and we might be
able to give you concrete answers.
