Guess a device's IP by knowing the MAC address

Is there anyway to know the IP address a device has in my LAN by only knowing it's mac address?

Thanks

How about sweeping your network's IP range(s) and see which machine corresponds to the given MAC?

if you and them are in the same subnet you could do
nmap -sP 192.168.1.0/24
and get all the ips that are up on the network, and then
arp ip
to get the mac addresses

edit: fixed some nonsensical typos

Take a look at rarp and arping. You can't use those with a standard Arch kernel though.
