Which company owns MAC address prefix 64:0E:9B?

MAC address prefix 64:0E:9B is registered to ISHIDA MEDICAL CO., LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 64:0E:9B has a network interface built by ISHIDA MEDICAL CO., LTD..

What is the OUI 64:0E:9B?

64:0E:9B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ISHIDA MEDICAL CO., LTD.. It covers every address from 64:0E:9B:00:00:00 to 64:0E:9B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 64-0E-9B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:0E:9B:00:00:00 that is 64:0E:9B — 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 ISHIDA MEDICAL CO., LTD. located?
