Which company owns MAC address prefix 8C:BE:24?

MAC address prefix 8C:BE:24 is registered to Tashang Semiconductor(Shanghai) Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 8C:BE:24 has a network interface built by Tashang Semiconductor(Shanghai) Co., Ltd..

What is the OUI 8C:BE:24?

8C:BE:24 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tashang Semiconductor(Shanghai) Co., Ltd.. It covers every address from 8C:BE:24:00:00:00 to 8C:BE:24:FF:FF:FF, or 16,777,216 addresses in total. It is also written 8C-BE-24.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 8C:BE:24:00:00:00 that is 8C:BE:24 — 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 Tashang Semiconductor(Shanghai) Co., Ltd. located?

Tashang Semiconductor(Shanghai) Co., Ltd. is listed at Room 903, Building 5, Minggu Science Park,No. 7001, Zhong Chun Road, Minhang District ,Shanghai 201101, P.R. China Shanghai CN 123456 in the IEEE OUI registry entry for 8C:BE:24. This is the address the organization registered with the IEEE, which may differ from its current operating address.
