If the servers are 10.20.30.40 and 10.20.30.41, does "host 10.20.30.40" return the name of the one server, and does "host 10.20.30.41" return the name of the other? That's reverse DNS, mapping an IP address back to the name of the host. (Use nslookup or dig instead of host, equivalently.)

I'm sorry but you are so loosing me on this. You can't use nslookup on internal private IPs can you?

You can try, but it's a long shot. Some servers are slow when reverse DNS is missing. Depends on the origanization whether there is any attempt to maintain reverse DNS; for a large organization, it might make sense to require everyone to have reverse DNS, even on an internal private network.

These are both Unix servers and they don't use DNS.
