Which company owns MAC address prefix 44:B3:82?

MAC address prefix 44:B3:82 is registered to Kuang-chi Institute of Advanced Technology in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 44:B3:82 has a network interface built by Kuang-chi Institute of Advanced Technology.

What is the OUI 44:B3:82?

44:B3:82 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Kuang-chi Institute of Advanced Technology. It covers every address from 44:B3:82:00:00:00 to 44:B3:82:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-B3-82.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:B3:82:00:00:00 that is 44:B3:82 — 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 Kuang-chi Institute of Advanced Technology located?

Kuang-chi Institute of Advanced Technology is listed at Software building, Gaoxingzhong 1st Road, Shenzhen Guangdong CN 518057 in the IEEE OUI registry entry for 44:B3:82. This is the address the organization registered with the IEEE, which may differ from its current operating address.
