About MAC Addresses

MAC addresses are 48-bit identifiers assigned to network interfaces
The first 24 bits identify the manufacturer (OUI)
The last 24 bits are unique to each device
Unicast addresses are for single devices, multicast for groups
Locally administered addresses are for private network use
