MAC addresses: What does UAA stand for?

Universally Administered Address

MAC addresses: What does LAA stand for?

Locally Administered Address

What is the 7th bit of a MAC address called?

U/L bit (Universal/Local bit)

If the U/L bit of a MAC address is […], it is a UAA.

0

If the U/L bit of a MAC address is 0, it is a […]AA.

U

If the U/L bit of a MAC address is […], it is an LAA.

1

If the U/L bit of a MAC address is 1, it is a […]AA.

L
