Which company owns MAC address prefix 04:4A:C6?

MAC address prefix 04:4A:C6 is registered to Aipon Electronics Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:4A:C6 has a network interface built by Aipon Electronics Co., Ltd.

What is the OUI 04:4A:C6?

04:4A:C6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Aipon Electronics Co., Ltd. It covers every address from 04:4A:C6:00:00:00 to 04:4A:C6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-4A-C6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:4A:C6:00:00:00 that is 04:4A:C6 — 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 Aipon Electronics Co., Ltd located?

Aipon Electronics Co., Ltd is listed at #78, Qiaojiao Dong road, Qiaolong, Tangxia Town Dongguan City Guangdong Province CN 523-710 in the IEEE OUI registry entry for 04:4A:C6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
