Which company owns MAC address prefix B0:6A:41?

MAC address prefix B0:6A:41 is registered to Google, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:6A:41 has a network interface built by Google, Inc..

What is the OUI B0:6A:41?

B0:6A:41 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Google, Inc.. It covers every address from B0:6A:41:00:00:00 to B0:6A:41:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-6A-41.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:6A:41:00:00:00 that is B0:6A:41 — 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 Google, Inc. located?

Google, Inc. is listed at 1600 Amphitheatre Parkway Mountain View CA US 94043 in the IEEE OUI registry entry for B0:6A:41. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Google, Inc. own?

Google, Inc. holds 110 OUI prefixes in the IEEE registry, of which B0:6A:41 is one. A device made by Google, Inc. could carry a MAC address from any of them.
