Which company owns MAC address prefix DC:3E:51?

MAC address prefix DC:3E:51 is registered to Solberg & Andersen AS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:3E:51 has a network interface built by Solberg & Andersen AS.

What is the OUI DC:3E:51?

DC:3E:51 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Solberg & Andersen AS. It covers every address from DC:3E:51:00:00:00 to DC:3E:51:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-3E-51.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:3E:51:00:00:00 that is DC:3E:51 — 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 Solberg & Andersen AS located?

Solberg & Andersen AS is listed at Litleaasvegen 61 Bergen NO 5132 in the IEEE OUI registry entry for DC:3E:51. This is the address the organization registered with the IEEE, which may differ from its current operating address.
