Reverse DNS on non-network .0 addresses

[Simon Waters]

Look okay from here.

13:54:22 srw srw $ dig +short @ns.a1com.net -x 66.153.40.0
network.buf.a1com.net.

However the delegation of the reverse lookup domain is
incomplete, so it won't work from anywhere else.

13:54:37 srw srw $ dig +short -x 66.153.40.0
13:54:45 srw srw $
