Which company owns MAC address prefix 00:10:D2?

MAC address prefix 00:10:D2 is registered to NITTO TSUSHINKI CO., LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:10:D2 has a network interface built by NITTO TSUSHINKI CO., LTD.

What is the OUI 00:10:D2?

00:10:D2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NITTO TSUSHINKI CO., LTD. It covers every address from 00:10:D2:00:00:00 to 00:10:D2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-10-D2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:10:D2:00:00:00 that is 00:10:D2 — 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 NITTO TSUSHINKI CO., LTD located?

NITTO TSUSHINKI CO., LTD is listed at 7-27-11, TODOROKI, SETAGAYA-KU TOKYO 151 JP in the IEEE OUI registry entry for 00:10:D2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
