A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.
MAC address is 48 bit long. It is in Hex (6 group - 2 Hexadecimal number in each).
Examples of MAC address
1. 48-2C-6A-1E-59-3D
2. 12-34-56-78-9A-BC
