Which company owns MAC address prefix F0:95:F1?

MAC address prefix F0:95:F1 is registered to Carl Zeiss AG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:95:F1 has a network interface built by Carl Zeiss AG.

What is the OUI F0:95:F1?

F0:95:F1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Carl Zeiss AG. It covers every address from F0:95:F1:00:00:00 to F0:95:F1:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-95-F1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:95:F1:00:00:00 that is F0:95:F1 — 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 Carl Zeiss AG located?

Carl Zeiss AG is listed at Carl-Zeiss-Straße 22 Oberkochen DE 73447 in the IEEE OUI registry entry for F0:95:F1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
