Which company owns MAC address prefix 00:13:95?

MAC address prefix 00:13:95 is registered to congatec GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:13:95 has a network interface built by congatec GmbH.

What is the OUI 00:13:95?

00:13:95 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to congatec GmbH. It covers every address from 00:13:95:00:00:00 to 00:13:95:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-13-95.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:13:95:00:00:00 that is 00:13:95 — 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 congatec GmbH located?

congatec GmbH is listed at Auwiesenstrasse 5 Deggendorf DE 94469 in the IEEE OUI registry entry for 00:13:95. This is the address the organization registered with the IEEE, which may differ from its current operating address.
