Which company owns MAC address prefix AC:FC:82?

MAC address prefix AC:FC:82 is registered to Shenzhen Sundray Technologies company Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:FC:82 has a network interface built by Shenzhen Sundray Technologies company Limited.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:FC:82:00:00:00 that is AC:FC:82 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

How many MAC prefixes does Shenzhen Sundray Technologies company Limited own?

Shenzhen Sundray Technologies company Limited holds 14 OUI prefixes in the IEEE registry, of which AC:FC:82 is one. A device made by Shenzhen Sundray Technologies company Limited could carry a MAC address from any of them.
