Which company owns MAC address prefix 6C:1F:F7?

MAC address prefix 6C:1F:F7 is registered to Ugreen Group Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 6C:1F:F7 has a network interface built by Ugreen Group Limited.

What is the OUI 6C:1F:F7?

6C:1F:F7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ugreen Group Limited. It covers every address from 6C:1F:F7:00:00:00 to 6C:1F:F7:FF:FF:FF, or 16,777,216 addresses in total. It is also written 6C-1F-F7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 6C:1F:F7:00:00:00 that is 6C:1F:F7 — 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.
