While the IP address is logical and it can be changed by the network administrator, the MAC address is on the hardware and it is permanent. The MAC address is registered on the network card when it is created in the factory. MAC ID (Media Access Control) is a unique digital number assigned to each computer on the network, more precisely not to a computer, but to a network card.
