What is the OUI 6C:92:BF?

6C:92:BF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to IEIT SYSTEMS Co., Ltd.. It covers every address from 6C:92:BF:00:00:00 to 6C:92:BF:FF:FF:FF, or 16,777,216 addresses in total. It is also written 6C-92-BF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 6C:92:BF:00:00:00 that is 6C:92:BF — 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.
