Finding an IP address by MAC address

Question

I know this question has been asked before and that and my own findings rely on using the ARP functionality.

The problem is that ARP only contains entries of IP/MAC addresses that have been “initialized” by some application/code. It could even be as simple as just a ping.

I came across reverse ARP (NARP?) but could not find any sample code for it anywhere.

Is it possible to acquire an IP address by just knowing the MAC address?

I could ping the whole su.net, but that would be inefficient.

Answer 1

I don't know how to integrate terminal command results on C# but I know you can get just the IP address scanning the Mac on your local.network by implementing this command on a terminal.

sudo arp-scan --localnet | awk '/b8:27:/ { print $1 }'
