Which company owns MAC address prefix AC:0D:FE?

MAC address prefix AC:0D:FE is registered to Ekon GmbH - myGEKKO in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:0D:FE has a network interface built by Ekon GmbH - myGEKKO.

What is the OUI AC:0D:FE?

AC:0D:FE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ekon GmbH - myGEKKO. It covers every address from AC:0D:FE:00:00:00 to AC:0D:FE:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-0D-FE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:0D:FE:00:00:00 that is AC:0D:FE — 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 Ekon GmbH - myGEKKO located?

Ekon GmbH - myGEKKO is listed at Rienzfeldstraße 30 Bruneck Südtirol (BZ) IT 39031 in the IEEE OUI registry entry for AC:0D:FE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
