What this block covers

The retired predecessor to MA-S, the same size and issued from a handful of IEEE owned prefixes. No new IABs have been issued since 2014, but existing ones remain valid.

Any MAC address between 40:D8:55:15:A0:00 and 40:D8:55:15:AF:FF belongs to this assignment. The registrant chooses the remaining 12 bits, so the same prefix can appear on very different products from the same company.
