Get Mac Address Of Local System Get Mac Address Of Remote But Same Network System. We can use Nmap to get mac address of a host if we are in the same network segment. $ sudo nmap -sP -n Get Mac Address Of Remote But Same Network System Get Mac Address Of Remote System With Snmp. The more complicated way is using SNMP service. Once you have identified the MAC addresses that you wish to scan, feed the corresponding IP addresses to nmap for scanning.
