What is the OUI F4:31:49?

F4:31:49 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Pixel FX. It covers every address from F4:31:49:00:00:00 to F4:31:49:FF:FF:FF, or 16,777,216 addresses in total. It is also written F4-31-49.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F4:31:49:00:00:00 that is F4:31:49 — 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 Pixel FX located?

Pixel FX is listed at 8001 Moore Road Indianapolis IN US 46278 in the IEEE OUI registry entry for F4:31:49. This is the address the organization registered with the IEEE, which may differ from its current operating address.
