Which company owns MAC address prefix B0:2F:20?

MAC address prefix B0:2F:20 is registered to VIM technology CO., LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:2F:20 has a network interface built by VIM technology CO., LTD..

What is the OUI B0:2F:20?

B0:2F:20 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to VIM technology CO., LTD.. It covers every address from B0:2F:20:00:00:00 to B0:2F:20:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-2F-20.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:2F:20:00:00:00 that is B0:2F:20 — 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 VIM technology CO., LTD. located?

VIM technology CO., LTD. is listed at 8F-3, No. 872, Zhongzheng Rd., Zhonghe Dist. New Taipei City TW 235015 in the IEEE OUI registry entry for B0:2F:20. This is the address the organization registered with the IEEE, which may differ from its current operating address.
