Which company owns MAC address prefix 0C:BF:3F?

MAC address prefix 0C:BF:3F is registered to Shenzhen Lencotion Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:BF:3F has a network interface built by Shenzhen Lencotion Technology Co.,Ltd.

What is the OUI 0C:BF:3F?

0C:BF:3F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Lencotion Technology Co.,Ltd. It covers every address from 0C:BF:3F:00:00:00 to 0C:BF:3F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-BF-3F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:BF:3F:00:00:00 that is 0C:BF:3F — 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 Shenzhen Lencotion Technology Co.,Ltd located?

Shenzhen Lencotion Technology Co.,Ltd is listed at LongGang,Buji Xia Shuijing,Hubei Baofeng Lndustrial Area,2/F,TowerB shenzhen Guangdong CN 518112 in the IEEE OUI registry entry for 0C:BF:3F.
