What this block covers
A 36 bit block, the smallest the IEEE sells. Suited to low volume products that will never ship 4096 units of anything.
Any MAC address between 8C:1F:64:58:40:00 and 8C:1F:64:58:4F: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.
