What is the OUI F8:9D:9D?

F8:9D:9D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen MinewSemi Co.,LTD.. It covers every address from F8:9D:9D:00:00:00 to F8:9D:9D:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-9D-9D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:9D:9D:00:00:00 that is F8:9D:9D — 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.
