Which company owns MAC address prefix 8C:41:F4?

MAC address prefix 8C:41:F4 is registered to IPmotion GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 8C:41:F4 has a network interface built by IPmotion GmbH.

What is the OUI 8C:41:F4?

8C:41:F4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to IPmotion GmbH. It covers every address from 8C:41:F4:00:00:00 to 8C:41:F4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 8C-41-F4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 8C:41:F4:00:00:00 that is 8C:41:F4 — 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 IPmotion GmbH located?

IPmotion GmbH is listed at Ludwig-Rinn-Straße 8-16 Heuchelheim Hessen DE 35452 in the IEEE OUI registry entry for 8C:41:F4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
