Moreover, a non-existent host is signaled by ICMP errors in normal operation. Say your packet reaches the router attached to network containing target IP address and there's no host on that very IP address. Then router will issue an ARP request and won't get any answer. In this case, it should send back a Host Unreachable ICMP message. It's a very common mistake around to think that probing non existing hosts don't generate any answer... -- http://sid.rstack.org/ PGP KeyID: 157E98EE FingerPrint: FA62226DA9E72FA8AECAA240008B480E157E98EE >> Hi!
