Which company owns MAC address prefix 00:0F:15?

MAC address prefix 00:0F:15 is registered to Icotera A/S in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0F:15 has a network interface built by Icotera A/S.

What is the OUI 00:0F:15?

00:0F:15 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Icotera A/S. It covers every address from 00:0F:15:00:00:00 to 00:0F:15:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0F-15.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0F:15:00:00:00 that is 00:0F:15 — 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 Icotera A/S located?

Icotera A/S is listed at Vibeholms Allé 12 Brøndby DK 2605 in the IEEE OUI registry entry for 00:0F:15. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Icotera A/S own?

Icotera A/S holds 3 OUI prefixes in the IEEE registry, of which 00:0F:15 is one. A device made by Icotera A/S could carry a MAC address from any of them.
