Hi Chris
Not sure what you mean with "locate hosts". I know that you can watch
the TTL's of packets to make assumptions on how many hopts they
passed. For example if you want to find out hosts that are behind a
NATing device packets you will see that the IP packets from the device
behind the NATing device will have a TTL which is one less than the
TTL of packets comming directly from the NAT device.
