Is there anyway to find if two different IP address in two different network actually points to the same physical device? I need it in Linux.

Edit -

I have the same server(a raspberry pi) connected via 2 intranets to my client. I don't know the IP address of the server as it is DHCP.

The crude way to do is to reach the raspberry pi from one intranet and check with ifconfig to find the ipadress of the machine in the other Intranet. I want to know if there is any other way I can do it?

I know the mac address of the machine.But I don't know how do I find the Ipadress based on the mac address.
