Host name from IP address

[Michael Jewett]

again, I think I'm not explaining myself clearly.  I want to be able to 
get the host_name in the hosts.cfg file, like this:

define host{
         use                     edgeswitch-host
         host_name               5510-Toole
         alias                   Toole 5510
         address                 172.16.24.28
         }

So I give the IP address 172.16.24.28 and I get 5510-Toole as the 
returned value.

Is it possible?

Michael
