Which company owns MAC address prefix BC:3E:CB?

MAC address prefix BC:3E:CB is registered to vivo Mobile Communication Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:3E:CB has a network interface built by vivo Mobile Communication Co., Ltd..

What is the OUI BC:3E:CB?

BC:3E:CB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to vivo Mobile Communication Co., Ltd.. It covers every address from BC:3E:CB:00:00:00 to BC:3E:CB:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-3E-CB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:3E:CB:00:00:00 that is BC:3E:CB — 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 vivo Mobile Communication Co., Ltd. located?

vivo Mobile Communication Co., Ltd. is listed at No.1, vivo Road, Chang'an Dongguan Guangdong CN 523860 in the IEEE OUI registry entry for BC:3E:CB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
