Which company owns MAC address prefix 10:B9:F7?

MAC address prefix 10:B9:F7 is registered to Niko-Servodan in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:B9:F7 has a network interface built by Niko-Servodan.

What is the OUI 10:B9:F7?

10:B9:F7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Niko-Servodan. It covers every address from 10:B9:F7:00:00:00 to 10:B9:F7:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-B9-F7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:B9:F7:00:00:00 that is 10:B9:F7 — 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 Niko-Servodan located?

Niko-Servodan is listed at Stenager 5 Sønderborg DK 6400 in the IEEE OUI registry entry for 10:B9:F7. This is the address the organization registered with the IEEE, which may differ from its current operating address.
