>From what I can recall from IP 101 I did years ago .. Pinging a host will still resolve an IP to MAC (ARP), the host may not echo the ICMP back.. But you should still get an ARP table entry on the requestor.. Am I wrong?

What about trying to do a sniff of some sort on the network, to see if the machine has any kind of trafic ?
