I need help understanding MAC address convention as described here. If I understand it correctly, then MAC address **00-27-C7-38-42-11**:

- Has 00 as the most significant byte.
- Has 0 (zero) set in its least significant bit of the most significant byte -- 00 Hex is 0000 0000 in binary.
- And therefore it's universally administered.

While MAC address **A9-5E-4C-22-AF-17**:

Has A9 as the most significant byte.

Has 1 (one) set in its least significant bit of the most significant byte -- A9 Hex is 1010 1001 in binary.

And therefore it's locally administered.

With that;

Is my understanding correct?

The the above MAC addresses are all 6 bytes and contain no unicast/multicast bit field. Is this correct?
