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 70:B3:D5:9A:A0:00 and 70:B3:D5:9A: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.
