Which company owns MAC address prefix 08:68:D0?

MAC address prefix 08:68:D0 is registered to Japan System Design in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:68:D0 has a network interface built by Japan System Design.

What is the OUI 08:68:D0?

08:68:D0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Japan System Design. It covers every address from 08:68:D0:00:00:00 to 08:68:D0:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-68-D0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:68:D0:00:00:00 that is 08:68:D0 — 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 Japan System Design located?

Japan System Design is listed at Skyhills Deshio 3F Hiroshima JP 734-0001 in the IEEE OUI registry entry for 08:68:D0. This is the address the organization registered with the IEEE, which may differ from its current operating address.
