About MAC Addresses
Structure
A MAC address is a 48-bit unique identifier. The first 24 bits (OUI) identify the manufacturer, and the last 24 bits are assigned by the manufacturer.
Unicast vs Multicast
The least significant bit of the first octet determines if the address is unicast (0) or multicast (1). Generated addresses are typically unicast.
Local vs Universal
The second least significant bit of the first octet determines if the address is universally administered (0) or locally administered (1).
