Reverse DNS on non-network .0 addresses

[Chris Tata]

Thanks for the quick reply!

Here is the other relevant information in this situation:

66.153.40.0/22

The zone I am doing reverse on:
zone "42.153.66.in-addr.arpa"{ type master; file "66.153.42";
allow-transfer{ 66.153.40.5; }; allow-update{ none;};};

@               IN      SOA     ns.a1com.net.   hostmaster.a1com.net. (
                        2002013102 ; serial
                        86400 ; refresh
                        3600 ; retry
                        3600000 ; expire
                        604800 ; default_ttl
                        )
@               IN      NS      ns.a1com.net.
@               IN      NS      ns2.a1com.net.
0              IN      PTR     reverse.domain.com.

Thanks,
