[GLLUG] Scanning MAC address for IP

[Melson, Paul]

A cheesy way to do this is to run `nmap -sP [network]/[mask]` and then
run `arp -a | grep -i [MAC address]` to see if you hit on anything.
Perhaps a better, but slower, way is to use tcpdump or snoop and filter
captured packets for the MAC address you're curious about.  Keep in mind
that if you're connected to a routed network, the MAC address you are
seeing may be that of a router interface connected to your LAN, so the
MAC address may not the best way to track traffic back to a host.

Does anyone know how to scan a known MAC address to see what IP it has? 
  Is there a nifty *nix tool that does this and I don't know how to?
