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 0C:47:A9:E0:00:00 and 0C:47:A9:EF: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.
