Which company owns MAC address prefix B0:D7:CC?

MAC address prefix B0:D7:CC is registered to Tridonic GmbH & Co KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:D7:CC has a network interface built by Tridonic GmbH & Co KG.

What is the OUI B0:D7:CC?

B0:D7:CC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tridonic GmbH & Co KG. It covers every address from B0:D7:CC:00:00:00 to B0:D7:CC:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-D7-CC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:D7:CC:00:00:00 that is B0:D7:CC — 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 Tridonic GmbH & Co KG located?

Tridonic GmbH & Co KG is listed at Färbergasse 15 Dornbirn Vorarlberg AT 6851 in the IEEE OUI registry entry for B0:D7:CC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
