Is there anyway to find the IP address of a MAC address using a command? I was thinking something like
arping might work but can't seem to find much information on it.
If the NIC owning the MAC is on the same network: Yes.
If the PC is not only the local network it gets a lot trickier. You might need to log into switches. What you can do and which commands you need for that differ per device.
Could be a few ways. If on a DHCP server and the client in question is getting an address, the mac will be listed in the lease information in the DHCP console or database.
If the client is attached to a Cisco switch, you could check the sh arp output on the switch and see if the mac is listed.
