address. Both commands may display different MAC address but one device is
assigned to each single network card. Window O.S may maintain more than one MAC
address against each network card, which is not associated with hardware of the
device. Some VPN clients have their own MAC address. MAC address of these
virtual network cards possess, same length and format as MAC address of computer
hardware.

operating systems:

The strategy of finding MAC address in Unix
and Linux O.S depends upon its versions. In some versions of Linux and Unix
