: For a change to take effect, the "locally administered" bit in the first octet must be set to 1. This tells the system the address is custom rather than factory-assigned.
For practical use, 02 , 06 , 0A , 12 , 1A , 22 , 2A , 32 , 3A , 42 , 4A , 52 , 5A , 62 , 6A , 72 , 7A , 82 , 8A , 92 , 9A , A2 , AA , B2 , BA , C2 , CA , D2 , DA , E2 , EA , F2 , or FA are easy to remember. For example, changing the first octet to 02 (binary 00000010 – unicast, locally administered) while leaving the remaining five octets as desired will typically succeed on most wireless drivers. Using 0A (binary 00001010 ) also works. Conversely, any attempt to set the first octet to 00 , 01 , 04 , 05 , 08 , 09 , 0C , 0D , etc., will fail. : For a change to take effect, the
