Which company owns MAC address prefix 00:01:37?

MAC address prefix 00:01:37 is registered to IT Farm Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:01:37 has a network interface built by IT Farm Corporation.

What is the OUI 00:01:37?

00:01:37 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to IT Farm Corporation. It covers every address from 00:01:37:00:00:00 to 00:01:37:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-01-37.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:01:37:00:00:00 that is 00:01:37 — 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 IT Farm Corporation located?

IT Farm Corporation is listed at Asashiseimei Fuchu Bldg. 11F 183-0055 JP in the IEEE OUI registry entry for 00:01:37. This is the address the organization registered with the IEEE, which may differ from its current operating address.
