in-addr.arpa zone for subclass 'c' network

[Kevin Darcy]

If you don't care to have reverse lookups for some of the addresses in your
range, it's no big deal. Just omit the PTR records. As for your network,
gateway and broadcast addresses, point the PTR's to anything you want. Will
anything actually be trying to reverse-resolve those addresses?
