Which company owns MAC address prefix F8:EA:0A?

MAC address prefix F8:EA:0A is registered to Dipl.-Math. Michael Rauch in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:EA:0A has a network interface built by Dipl.-Math. Michael Rauch.

What is the OUI F8:EA:0A?

F8:EA:0A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Dipl.-Math. Michael Rauch. It covers every address from F8:EA:0A:00:00:00 to F8:EA:0A:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-EA-0A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:EA:0A:00:00:00 that is F8:EA:0A — 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 Dipl.-Math. Michael Rauch located?

Dipl.-Math. Michael Rauch is listed at Kapellenstraße 31 Bretten BaWü DE 75015 in the IEEE OUI registry entry for F8:EA:0A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
