Actually this is effectively a broadcast/multicast MAC address.

The first byte of your MAC address should always be an even number. The value of the second bit is supposed to indicate if the MAC is "burned-in" and basically doesn't matter. The LSB of the first byte, however, should always be zero.

You say "actually" but you seem to be agreeing with me.

The first byte of my bad MAC is '01'. This not even because the LSB is set, making it a multicast address which is bad.
