What this block covers
The classic 24 bit OUI. The registrant owns the first three octets and can assign every one of the remaining 16.7 million addresses.
Any MAC address between 74:D7:CA:00:00:00 and 74:D7:CA:FF:FF:FF belongs to this assignment. The registrant chooses the remaining 24 bits, so the same prefix can appear on very different products from the same company.
