Which company owns MAC address prefix CC:0C:DA?

MAC address prefix CC:0C:DA is registered to Miljovakt AS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:0C:DA has a network interface built by Miljovakt AS.

What is the OUI CC:0C:DA?

CC:0C:DA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Miljovakt AS. It covers every address from CC:0C:DA:00:00:00 to CC:0C:DA:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-0C-DA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:0C:DA:00:00:00 that is CC:0C:DA — 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 Miljovakt AS located?

Miljovakt AS is listed at Gannestadveien 2 Borre Vestfold NO 3184 in the IEEE OUI registry entry for CC:0C:DA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
