Which company owns MAC address prefix 10:09:0C?

MAC address prefix 10:09:0C is registered to JANOME Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:09:0C has a network interface built by JANOME Corporation.

What is the OUI 10:09:0C?

10:09:0C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JANOME Corporation. It covers every address from 10:09:0C:00:00:00 to 10:09:0C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-09-0C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:09:0C:00:00:00 that is 10:09:0C — 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 JANOME Corporation located?

JANOME Corporation is listed at 1463 Hazama-Machi Hachioji-Shi Tokyo JP 193-0941 in the IEEE OUI registry entry for 10:09:0C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
