Which company owns MAC address prefix B8:B2:EB?

MAC address prefix B8:B2:EB is registered to Googol Technology (HK) Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:B2:EB has a network interface built by Googol Technology (HK) Limited.

What is the OUI B8:B2:EB?

B8:B2:EB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Googol Technology (HK) Limited. It covers every address from B8:B2:EB:00:00:00 to B8:B2:EB:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-B2-EB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:B2:EB:00:00:00 that is B8:B2:EB — 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 Googol Technology (HK) Limited located?

Googol Technology (HK) Limited is listed at Unit 1008-09, 10/F C-Bons International Center Kwun Tong Kowloon HK nil in the IEEE OUI registry entry for B8:B2:EB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
