Which company owns MAC address prefix 94:DE:0E?

MAC address prefix 94:DE:0E is registered to SmartOptics AS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:DE:0E has a network interface built by SmartOptics AS.

What is the OUI 94:DE:0E?

94:DE:0E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SmartOptics AS. It covers every address from 94:DE:0E:00:00:00 to 94:DE:0E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-DE-0E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:DE:0E:00:00:00 that is 94:DE:0E — 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 SmartOptics AS located?

SmartOptics AS is listed at Stalfjaera 9 Oslo NO N-0975 in the IEEE OUI registry entry for 94:DE:0E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
