Which company owns MAC address prefix CC:F3:05?

MAC address prefix CC:F3:05 is registered to SHENZHEN TIAN XING CHUANG ZHAN ELECTRONIC CO.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:F3:05 has a network interface built by SHENZHEN TIAN XING CHUANG ZHAN ELECTRONIC CO.,LTD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:F3:05:00:00:00 that is CC:F3:05 — 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.
