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 8C:59:3C:70:00:00 and 8C:59:3C:7F: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.
