I would say _supposed_ to be unique. Surely some cheapo manufacturer has recycled addresses from their old ISA card days. Back in the mainframe days, admins used to always set the MAC addresses of devices on the token rings, since the MAC address was used to bid on which node managed the ring. I have seen people fat-finger it too.
