Are there any methods by which a server can reverse lookup ip addresses that
have been handed out by dhcp?  In other words, if my dhcp server hands out
an address, then future lookups on that address should resolve to whatever
hostname is present in the dhcpd.leases file.

Of course I say 'should', but it's more of a 'could?'  What about some way
to automatically populate the hosts file with assigned dhcp addresses?

Can you tell that I don't know what to ask because I don't know what's
possible?

Help?
