Which company owns MAC address prefix F0:3F:F8?

MAC address prefix F0:3F:F8 is registered to R L Drake in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:3F:F8 has a network interface built by R L Drake.

What is the OUI F0:3F:F8?

F0:3F:F8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to R L Drake. It covers every address from F0:3F:F8:00:00:00 to F0:3F:F8:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-3F-F8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:3F:F8:00:00:00 that is F0:3F:F8 — 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 R L Drake located?

R L Drake is listed at 1 Jake Brown Road Old Bridge NJ US 08857 in the IEEE OUI registry entry for F0:3F:F8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
