What is the OUI F4:6A:BC?

F4:6A:BC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Adonit Corp. Ltd.. It covers every address from F4:6A:BC:00:00:00 to F4:6A:BC:FF:FF:FF, or 16,777,216 addresses in total. It is also written F4-6A-BC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F4:6A:BC:00:00:00 that is F4:6A:BC — 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.
