Which company owns MAC address prefix DC:DC:07?

MAC address prefix DC:DC:07 is registered to TRP Systems BV in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:DC:07 has a network interface built by TRP Systems BV.

What is the OUI DC:DC:07?

DC:DC:07 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TRP Systems BV. It covers every address from DC:DC:07:00:00:00 to DC:DC:07:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-DC-07.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:DC:07:00:00:00 that is DC:DC:07 — 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 TRP Systems BV located?

TRP Systems BV is listed at Televisieweg 159 1322 BH Almere Almere - NL - in the IEEE OUI registry entry for DC:DC:07. This is the address the organization registered with the IEEE, which may differ from its current operating address.
