Which company owns MAC address prefix D4:79:C3?

What is the OUI D4:79:C3?

D4:79:C3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Cameronet GmbH & Co. KG. It covers every address from D4:79:C3:00:00:00 to D4:79:C3:FF:FF:FF, or 16,777,216 addresses in total. It is also written D4-79-C3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D4:79:C3:00:00:00 that is D4:79:C3 — 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 Cameronet GmbH & Co. KG located?

Cameronet GmbH & Co. KG is listed at Elberfelder Strasse 96 Remscheid NRW DE 42853 in the IEEE OUI registry entry for D4:79:C3. This is the address the organization registered with the IEEE, which may differ from its current operating address.
