Can a device change its MAC address?

MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device. The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed.

Is MAC address same for every device?

The IEEE manages MAC addresses. The hardware identification addresses that the IEEE distributes are unique. … On the other hand, some hardware MAC addresses are programmable, which makes them spoofable. This means that it is possible for two machines in the same network to have the same MAC address.
