Which company owns MAC address prefix 6C:AF:15?

MAC address prefix 6C:AF:15 is registered to Webasto SE in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 6C:AF:15 has a network interface built by Webasto SE.

What is the OUI 6C:AF:15?

6C:AF:15 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Webasto SE. It covers every address from 6C:AF:15:00:00:00 to 6C:AF:15:FF:FF:FF, or 16,777,216 addresses in total. It is also written 6C-AF-15.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 6C:AF:15:00:00:00 that is 6C:AF:15 — 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 Webasto SE located?

Webasto SE is listed at Kraillinger Straße 5 Stockdorf Bayern DE 82131 in the IEEE OUI registry entry for 6C:AF:15. This is the address the organization registered with the IEEE, which may differ from its current operating address.
