Which company owns MAC address prefix 94:CA:9A?

MAC address prefix 94:CA:9A is registered to Paul Vahle GmbH & Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:CA:9A has a network interface built by Paul Vahle GmbH & Co. KG.

What is the OUI 94:CA:9A?

94:CA:9A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Paul Vahle GmbH & Co. KG. It covers every address from 94:CA:9A:00:00:00 to 94:CA:9A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-CA-9A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:CA:9A:00:00:00 that is 94:CA:9A — 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 Paul Vahle GmbH & Co. KG located?

Paul Vahle GmbH & Co. KG is listed at Westickerstr. 52 Kamen DE 59174 in the IEEE OUI registry entry for 94:CA:9A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
