Which company owns MAC address prefix 0C:AA:EE?

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

What is the OUI 0C:AA:EE?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:AA:EE:00:00:00 that is 0C:AA:EE — 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 Ansjer Electronics Co., Ltd. located?

Ansjer Electronics Co., Ltd. is listed at 4 Bldg., Pinglan Indl. Park, Nanping, Zhuhai Guangdong CN 519060 in the IEEE OUI registry entry for 0C:AA:EE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
