Which company owns MAC address prefix EC:98:6C?

MAC address prefix EC:98:6C is registered to Lufft Mess- und Regeltechnik GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:98:6C has a network interface built by Lufft Mess- und Regeltechnik GmbH.

What is the OUI EC:98:6C?

EC:98:6C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Lufft Mess- und Regeltechnik GmbH. It covers every address from EC:98:6C:00:00:00 to EC:98:6C:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-98-6C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:98:6C:00:00:00 that is EC:98:6C — 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 Lufft Mess- und Regeltechnik GmbH located?

Lufft Mess- und Regeltechnik GmbH is listed at Gutenbergstraße 20 Fellbach Baden-Württemberg DE 70736 in the IEEE OUI registry entry for EC:98:6C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
