Which company owns MAC address prefix 00:F2:2C?

MAC address prefix 00:F2:2C is registered to Shanghai B-star Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:F2:2C has a network interface built by Shanghai B-star Technology Co.,Ltd..

What is the OUI 00:F2:2C?

00:F2:2C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shanghai B-star Technology Co.,Ltd.. It covers every address from 00:F2:2C:00:00:00 to 00:F2:2C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-F2-2C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:F2:2C:00:00:00 that is 00:F2:2C — 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 Shanghai B-star Technology Co.,Ltd. located?

Shanghai B-star Technology Co.,Ltd. is listed at 4Floor NO.1158 Xiehe Road,Changning District ,shanghai ,China 200335 Shanghai CN 200335 in the IEEE OUI registry entry for 00:F2:2C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
