Which company owns MAC address prefix D8:C6:F9?

MAC address prefix D8:C6:F9 is registered to Tracklab Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:C6:F9 has a network interface built by Tracklab Inc.

What is the OUI D8:C6:F9?

D8:C6:F9 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tracklab Inc. It covers every address from D8:C6:F9:00:00:00 to D8:C6:F9:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-C6-F9.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:C6:F9:00:00:00 that is D8:C6:F9 — 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 Tracklab Inc located?

Tracklab Inc is listed at 5060 SW Philomath BLVD #508 CORVALLIS OR US 97333 in the IEEE OUI registry entry for D8:C6:F9. This is the address the organization registered with the IEEE, which may differ from its current operating address.
