Which company owns MAC address prefix 68:CD:0F?

MAC address prefix 68:CD:0F is registered to U Tek Company Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:CD:0F has a network interface built by U Tek Company Limited.

What is the OUI 68:CD:0F?

68:CD:0F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to U Tek Company Limited. It covers every address from 68:CD:0F:00:00:00 to 68:CD:0F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-CD-0F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:CD:0F:00:00:00 that is 68:CD:0F — 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.

Where is U Tek Company Limited located?
