Which company owns MAC address prefix F0:AF:50?

MAC address prefix F0:AF:50 is registered to Phantom Intelligence in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:AF:50 has a network interface built by Phantom Intelligence.

What is the OUI F0:AF:50?

F0:AF:50 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Phantom Intelligence. It covers every address from F0:AF:50:00:00:00 to F0:AF:50:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-AF-50.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:AF:50:00:00:00 that is F0:AF:50 — 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 Phantom Intelligence located?

Phantom Intelligence is listed at 319 Rue Franquet Suite F Quebec QC CA G1P 4R4 in the IEEE OUI registry entry for F0:AF:50. This is the address the organization registered with the IEEE, which may differ from its current operating address.
