What this block covers
A 24 bit identifier that looks like an OUI but is explicitly not for globally unique addresses. The local bit is set, so CID addresses are locally administered by definition.
Any MAC address between 4A:7F:74:00:00:00 and 4A:7F:74: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.
