Do you mean get the MAC address? If so MAC addresses aren't unique anymore, and how could you lookup what MAC address belongs to what IP?
Assuming that you're on the same local net as the machine you're interested in (but then, if you're not on the same local net, the MAC is difficult to obtain in the first place and probably won't do you much good), the arping tool from http://synscan.nss.nu/programs.php will find whatever IP(s) are associated with a MAC. It's quite a handy little tool - I've used it in the past to hunt down misbehaving hosts. Non-unique MACs? Wouldn't that break ethernet?

All scans are icmp or port 53 (domain). Mostly'they' firstsend a few icmp packets and then a scan for port 53 trying to do a reverse lookup for my ip. Are there more seeing this type off scans and is there a way to substract the real scanner (ip) from the list ip's ??? Greetings, Richard.
