Which company owns MAC address prefix CC:67:D8?

MAC address prefix CC:67:D8 is registered to Telin Semiconductor (Wuhan) Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:67:D8 has a network interface built by Telin Semiconductor (Wuhan) Co.,Ltd.

What is the OUI CC:67:D8?

CC:67:D8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Telin Semiconductor (Wuhan) Co.,Ltd. It covers every address from CC:67:D8:00:00:00 to CC:67:D8:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-67-D8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:67:D8:00:00:00 that is CC:67:D8 — 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 Telin Semiconductor (Wuhan) Co.,Ltd located?

Telin Semiconductor (Wuhan) Co.,Ltd is listed at Room 1003 Buliding 5 , 2377 Shenkun Road ,Minhang District Shanghai CN 201106 in the IEEE OUI registry entry for CC:67:D8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
