Which company owns MAC address prefix B8:64:68?

MAC address prefix B8:64:68 is registered to BBSakura Networks, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:64:68 has a network interface built by BBSakura Networks, Inc..

What is the OUI B8:64:68?

B8:64:68 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BBSakura Networks, Inc.. It covers every address from B8:64:68:00:00:00 to B8:64:68:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-64-68.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:64:68:00:00:00 that is B8:64:68 — 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 BBSakura Networks, Inc. located?

BBSakura Networks, Inc. is listed at Sumitomo Fudosan Nishishinjuku Building, 7-20-1 Nishi-shinjuku Shinjuku-ku Tokyo JP 160-0023 in the IEEE OUI registry entry for B8:64:68. This is the address the organization registered with the IEEE, which may differ from its current operating address.
