What this block covers
A 28 bit block. Sixteen of these fit inside one 24 bit prefix, so the first three octets are shared with other registrants.
Any MAC address between D4:20:00:C0:00:00 and D4:20:00:CF:FF:FF belongs to this assignment. The registrant chooses the remaining 20 bits, so the same prefix can appear on very different products from the same company.
