Which company owns MAC address prefix 10:D8:CC?

MAC address prefix 10:D8:CC is registered to Guangzhou FiiO Electronics Technology CO., LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:D8:CC has a network interface built by Guangzhou FiiO Electronics Technology CO., LTD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:D8:CC:00:00:00 that is 10:D8:CC — 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.
