You can find those here: http://standards.ieee.org/regauth/oui/index.shtml If you're talking about trying to take an IP address and obtain its MAC, it's only possible if the target is on the same logical network you are (I.e., a non-routed segment). In that case, arp -a in a shell will show you what you want. -- Mark C.
