Which company owns MAC address prefix 68:2D:DC?

MAC address prefix 68:2D:DC is registered to Wuhan Changjiang Electro-Communication Equipment CO.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:2D:DC has a network interface built by Wuhan Changjiang Electro-Communication Equipment CO.,LTD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:2D:DC:00:00:00 that is 68:2D:DC — 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.
