There is a specific command– “ipconfig” in latest versions
of the window to check MAC address. Old versions of window like 98 and window
99 used the command– “winipcfg”. Both commands may display different MAC
address for one device but there is only one address for one network card.
Window O.S may maintain more than one MAC address, which is not associated with
hardware of the device. Some VPN clients have their own MAC address. MAC
address of these virtual networks has same length and format as MAC address
computer hardware.

Searching MAC address in UNIX or LINUX operating

Some network cards allow user to set custom Mac address from
their configuration pane in Device manager, while others may not support this
feature.
