Which company owns MAC address prefix 00:07:17?

MAC address prefix 00:07:17 is registered to Wieland Electric GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:07:17 has a network interface built by Wieland Electric GmbH.

What is the OUI 00:07:17?

00:07:17 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Wieland Electric GmbH. It covers every address from 00:07:17:00:00:00 to 00:07:17:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-07-17.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:07:17:00:00:00 that is 00:07:17 — 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 Wieland Electric GmbH located?

Wieland Electric GmbH is listed at Brennerstraße 10-14 DE in the IEEE OUI registry entry for 00:07:17. This is the address the organization registered with the IEEE, which may differ from its current operating address.
