Which company owns MAC address prefix 94:C3:E4?

MAC address prefix 94:C3:E4 is registered to Atlas Copco IAS GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:C3:E4 has a network interface built by Atlas Copco IAS GmbH.

What is the OUI 94:C3:E4?

94:C3:E4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Atlas Copco IAS GmbH. It covers every address from 94:C3:E4:00:00:00 to 94:C3:E4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-C3-E4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:C3:E4:00:00:00 that is 94:C3:E4 — 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 Atlas Copco IAS GmbH located?

Atlas Copco IAS GmbH is listed at Gewerbestr. 52 Bretten-Goelshausen DE 75015 in the IEEE OUI registry entry for 94:C3:E4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
