Which company owns MAC address prefix D8:7C:DD?

MAC address prefix D8:7C:DD is registered to SANIX INCORPORATED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:7C:DD has a network interface built by SANIX INCORPORATED.

What is the OUI D8:7C:DD?

D8:7C:DD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SANIX INCORPORATED. It covers every address from D8:7C:DD:00:00:00 to D8:7C:DD:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-7C-DD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:7C:DD:00:00:00 that is D8:7C:DD — 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.

Where is SANIX INCORPORATED located?

SANIX INCORPORATED is listed at Creation Core Fukuoka 212, 3-2-16 Kamikoga, Chikushino-shi Fukuoka JP 818-0041 in the IEEE OUI registry entry for D8:7C:DD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
