Which company owns MAC address prefix CC:8C:DA?

MAC address prefix CC:8C:DA is registered to Shenzhen Wei Da Intelligent Technology Go.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:8C:DA has a network interface built by Shenzhen Wei Da Intelligent Technology Go.,Ltd.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:8C:DA:00:00:00 that is CC:8C:DA — 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.
