Which company owns MAC address prefix EC:FC:55?

MAC address prefix EC:FC:55 is registered to A. Eberle GmbH & Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:FC:55 has a network interface built by A. Eberle GmbH & Co. KG.

What is the OUI EC:FC:55?

EC:FC:55 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to A. Eberle GmbH & Co. KG. It covers every address from EC:FC:55:00:00:00 to EC:FC:55:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-FC-55.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:FC:55:00:00:00 that is EC:FC:55 — 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 A. Eberle GmbH & Co. KG located?

A. Eberle GmbH & Co. KG is listed at Frankenstrasse 160 Nuernberg Bavaria DE 90461 in the IEEE OUI registry entry for EC:FC:55. This is the address the organization registered with the IEEE, which may differ from its current operating address.
