Which company owns MAC address prefix 60:9B:2D?

MAC address prefix 60:9B:2D is registered to JMACS Japan Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:9B:2D has a network interface built by JMACS Japan Co., Ltd..

What is the OUI 60:9B:2D?

60:9B:2D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JMACS Japan Co., Ltd.. It covers every address from 60:9B:2D:00:00:00 to 60:9B:2D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-9B-2D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:9B:2D:00:00:00 that is 60:9B:2D — 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 JMACS Japan Co., Ltd. located?
