Which company owns MAC address prefix 94:A3:CA?

What is the OUI 94:A3:CA?

94:A3:CA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to KonnectONE, LLC. It covers every address from 94:A3:CA:00:00:00 to 94:A3:CA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-A3-CA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:A3:CA:00:00:00 that is 94:A3:CA — 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 KonnectONE, LLC located?

KonnectONE, LLC is listed at 30 N Gould Street STE 4004 Sheridan WY US 82801 in the IEEE OUI registry entry for 94:A3:CA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
