Which company owns MAC address prefix BC:D7:13?

MAC address prefix BC:D7:13 is registered to Owl Labs in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:D7:13 has a network interface built by Owl Labs.

What is the OUI BC:D7:13?

BC:D7:13 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Owl Labs. It covers every address from BC:D7:13:00:00:00 to BC:D7:13:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-D7-13.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:D7:13:00:00:00 that is BC:D7:13 — 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 Owl Labs located?

Owl Labs is listed at 33-1/2 Union Square Somerville MA US 02143 in the IEEE OUI registry entry for BC:D7:13. This is the address the organization registered with the IEEE, which may differ from its current operating address.
