In other words the hosts must have contacted each other at some point in time. Try this....run arp -a and look at the output then put a host on the network without "talking" to it. run arp -a again and you won't see it. Ping it and then run arp -a again and it will show up. I think that's why this program works. It must ping all adresses in the net range and then arp -a to see what shows. Geekmaster:
