How could I collect the MAC from a different network machine?

For example, from a machine on the 172.85.6.0/24 network I want to collect the MAC from a machine on the 192.168.6.0/24 network.

Read here, MAC addresses are visible on OSI layer 2.

If they are on same lan then you simply modify your subnet to a supernet.

If the networks are able to route packets between each network ping the device using the IP then inspect your ARP table

You need to be root

Code:

nmap -sP -n 192.168.0.0/24

You'll have to be able to reach other subnets from the machine you are on.

In previous releases of Nmap, -sn was known as -sP.
