Which company owns MAC address prefix 2C:B3:01?

MAC address prefix 2C:B3:01 is registered to Honor Device Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 2C:B3:01 has a network interface built by Honor Device Co., Ltd..

What is the OUI 2C:B3:01?

2C:B3:01 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Honor Device Co., Ltd.. It covers every address from 2C:B3:01:00:00:00 to 2C:B3:01:FF:FF:FF, or 16,777,216 addresses in total. It is also written 2C-B3-01.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 2C:B3:01:00:00:00 that is 2C:B3:01 — 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 Honor Device Co., Ltd. located?

Honor Device Co., Ltd. is listed at Suite 3401, Unit A, Building 6, Shum Yip Sky Park, No. 8089, Hongli West Road, Xiangmihu Street, Futian District Shenzhen Guangdong CN 518040 in the IEEE OUI registry entry for 2C:B3:01.
