Literally do not use an odd number in that first octet. If you
literally mean "ab" there, don't do it. That's an odd number and would
be an ethernet multicast address then. You might be best off always
setting the second digit of the first octel = 2, like 02, 12, 22, ...
a2 ... e2, f2. Those would be safe as "locally administered unicast
