Greetings!

I have a device on my network that I'm trying to ID. I can get the MAC address off the switch, and I need to get either the IP address or the name of the device. How do I do this using the MAC address?

Thanks in advance.

Mike
 
Download a copy of Network Magic to one system and let it discover the devices on your LAN. even after the trial period lapses, it will still keep the mapping current.

For every device discovered, there are details for the device
Mac addr, IP addr, and device/system info

You could try running an arp -a to get a listing of the ARP cache, but this will only display that address if you've had any kind of communication (including broadcasts) with that device. It's designed to go the other way around (IP to MAC) but can sometimes be used the way you want in a limited fasion.
