Which company owns MAC address prefix 68:2C:4F?

MAC address prefix 68:2C:4F is registered to leerang corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:2C:4F has a network interface built by leerang corporation.

What is the OUI 68:2C:4F?

68:2C:4F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to leerang corporation. It covers every address from 68:2C:4F:00:00:00 to 68:2C:4F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-2C-4F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:2C:4F:00:00:00 that is 68:2C:4F — 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.
