Which company owns MAC address prefix 3C:CB:01?

MAC address prefix 3C:CB:01 is registered to Beijing Lingji innovations Technology Co., LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 3C:CB:01 has a network interface built by Beijing Lingji innovations Technology Co., LTD..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 3C:CB:01:00:00:00 that is 3C:CB: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 Beijing Lingji innovations Technology Co., LTD. located?

Beijing Lingji innovations Technology Co., LTD. is listed at Room 106, 1F, A1 Bldg. Zhongguancun Dongsheng Technology Park (Northern Territory), No. 66, Xixiaokou Rd, Haidian Dist., Beijing, China Beijing Beijing CN 100192 in the IEEE OUI registry entry for 3C:CB:01. This is the address the organization registered with the IEEE, which may differ from its current operating address.
