It may not be special, but it is different. Reverse DNS uses PTR records, not A records. The site you referenced points this out, too: """ Reverse DNS entries are set up with PTR records (whereas standard DNS uses A records), which look like "25.2.0.192.in-addr.arpa. PTR host.example.com" (whereas standard DNS would look like "host.example.com. A 192.0.2.25"). """ Jp -- http://mail.python.org/mailman/listinfo/python-list
