Reading a MAC address
- OUI — the first 3 bytes identify the vendor that registered the address.
- I/G bit — the least significant bit of the first byte: 0 = unicast, 1 = multicast/broadcast.
- U/L bit — the second least significant bit of the first byte: 0 = globally unique (vendor), 1 = locally administered.
