Which company owns MAC address prefix 94:C0:14?

MAC address prefix 94:C0:14 is registered to Sorter Sp. j. Konrad Grzeszczyk MichaA, Ziomek in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:C0:14 has a network interface built by Sorter Sp. j. Konrad Grzeszczyk MichaA, Ziomek.

What is the OUI 94:C0:14?

94:C0:14 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sorter Sp. j. Konrad Grzeszczyk MichaA, Ziomek. It covers every address from 94:C0:14:00:00:00 to 94:C0:14:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-C0-14.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:C0:14:00:00:00 that is 94:C0:14 — 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 Sorter Sp. j. Konrad Grzeszczyk MichaA, Ziomek located?

Sorter Sp. j. Konrad Grzeszczyk MichaA, Ziomek is listed at ul. Gdynska 32 PL9482565081 Mazowieckie PL 26-600 in the IEEE OUI registry entry for 94:C0:14. This is the address the organization registered with the IEEE, which may differ from its current operating address.
