Lets say we have two networks A and B.
3 machines a,b,c. b is multihomed ie has one ethernet-interface
at both networks.
The networks is connected with a brouter so b doesn't run IPfw.

Network A is 192.168.1.xx
-"-         B is 192.168.2.xx

a has adress 192.168.1.1
b has adress 192.168.1.2 on network A
and adress 192.168.2.2 on network B
c has adress 192.168.2.1

a is known as a.localdomain
b is known as b.localdomain
c dito

b runs dns. What now ? a should be able to send requests to its dns server
for the IP-adress of b and c using the hostname b and c
c should be able to send requests to its dns server
for the IP-adress of b and a using the hostname b and a.

The reply to a with the adress of b should be a local adress ie 192.168.1.2
and c in the same case should get 192.168.2.2 ie the different answers to
the same
question if not for the source.
Which will happen if name-resolving on clients and dns server is correct.

This way messages to b doesn't need to go thru the brouter.

Reverse lookup on 192.168.2.2 and 192.168.1.2 should get the same answer ie
b.localdomain which is the main reason why getnamebyaddr must work.

Puhhhh
