Reverse ARP?

[Saulbadguy]

I'd like to find out the IP address of a device on our network. All I know is the MAC Address. How can I do this?

Look into a network sniffer and analysis program.

Should be able to capture all packets on a network segment and you'll be informed of everything possible about those particular network devices

sniff or look at the routers arp table and filter for that max.

there maybe a rarp program out there.
