Which company owns MAC address prefix C8:C4:32?

MAC address prefix C8:C4:32 is registered to SG Armaturen AS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:C4:32 has a network interface built by SG Armaturen AS.

What is the OUI C8:C4:32?

C8:C4:32 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SG Armaturen AS. It covers every address from C8:C4:32:00:00:00 to C8:C4:32:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-C4-32.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:C4:32:00:00:00 that is C8:C4:32 — 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 SG Armaturen AS located?

SG Armaturen AS is listed at Skytterheia 25, N-4790 Lillesand NO 4790 in the IEEE OUI registry entry for C8:C4:32. This is the address the organization registered with the IEEE, which may differ from its current operating address.
