Which company owns MAC address prefix BC:6A:2F?

MAC address prefix BC:6A:2F is registered to Henge Docks LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:6A:2F has a network interface built by Henge Docks LLC.

What is the OUI BC:6A:2F?

BC:6A:2F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Henge Docks LLC. It covers every address from BC:6A:2F:00:00:00 to BC:6A:2F:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-6A-2F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:6A:2F:00:00:00 that is BC:6A:2F — 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 Henge Docks LLC located?

Henge Docks LLC is listed at 455 10th St. San Francisco California US 94103 in the IEEE OUI registry entry for BC:6A:2F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
