MAC Address Format
A complete MAC address consists of 48 bits (6 bytes) and is typically represented in hexadecimal format with each byte separated by a colon or a hyphen. For Telecommunications Industry Association TR-41 Committee devices, the MAC address would look like:
00:12:BB:XX:XX:XX
The first three bytes (00:12:BB) identify the manufacturer as Telecommunications Industry Association TR-41 Committee, while the last three bytes are unique to each device.
