reverse DNS resolution...

Hey folks,

We're trying to get reverse DNS resolution for a block of IPs (private). We've had the 10.x network working great at the office for quite some time now, but I'm having a problem getting the 172.30.x network to work.

Typing 'host <ip>' returns a valid result, however output from who, as well as other network services (IRC, apache) only see the IP. Is there something I'm missing?

Thanks for the pointers!
