Who owns MAC address?

MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. Each address can be stored in hardware, such as the card's read-only memory, or by a firmware mechanism.

Can the police trace a MAC address?

This allows police to retrieve the unique MAC address of any stolen electronic wifi-enabled device, even after it has been stolen, or the serial numbers have been tampered with. This provides a means of locating the device and the possible arrest of an offender.
