reverse DNS resolution...

[Eric F Crist]

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!
