Which company owns MAC address prefix C0:07:4A?

MAC address prefix C0:07:4A is registered to Brita GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:07:4A has a network interface built by Brita GmbH.

What is the OUI C0:07:4A?

C0:07:4A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Brita GmbH. It covers every address from C0:07:4A:00:00:00 to C0:07:4A:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-07-4A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C0:07:4A:00:00:00 that is C0:07:4A — 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 Brita GmbH located?

Brita GmbH is listed at Heinrich-Hertz-Str. 4 Taunusstein DE 65232 in the IEEE OUI registry entry for C0:07:4A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
