Mac adresses staring with the first two or three bits set are something
special (broadcast,multicast ... )

More specifically - the low order bit of the first (high order) octet...

Please let you mac Address start with 00: or at least 0x: and try again.

... so 0x: is only safe if x is in {0, 2, 4, 6, 8, A, C, E}.

A generally safe format is yx:yy:yy:yy:yy:yy where y is any digit (0-F) and x is in {2, 6, A, E} (these are "locally assigned" address rather than "universal" addresses allocated to hardware vendors).
