Which company owns MAC address prefix 00:0C:72?

MAC address prefix 00:0C:72 is registered to Tempearl Industrial Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0C:72 has a network interface built by Tempearl Industrial Co., Ltd..

What is the OUI 00:0C:72?

00:0C:72 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tempearl Industrial Co., Ltd.. It covers every address from 00:0C:72:00:00:00 to 00:0C:72:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0C-72.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0C:72:00:00:00 that is 00:0C:72 — 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 Tempearl Industrial Co., Ltd. located?
