FAQ
- Which company owns MAC address prefix CC:CF:FE?
- MAC address prefix CC:CF:FE is registered to Henan Lingyunda Information Technology Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:CF:FE has a network interface built by Henan Lingyunda Information Technology Co., Ltd.
- What is the OUI CC:CF:FE?
- CC:CF:FE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Henan Lingyunda Information Technology Co., Ltd. It covers every address from CC:CF:FE:00:00:00 to CC:CF:FE:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-CF-FE.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in CC:CF:FE:00:00:00 that is CC:CF:FE — 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 Henan Lingyunda Information Technology Co., Ltd located?
- Henan Lingyunda Information Technology Co., Ltd is listed at Block B, Hanhai North Gold Commercial Center, No.73 North Third Ring Road, Jinshui District, Zhengzhou City, Henan Province Zhengzhou Henan Province CN 450000 in the IEEE OUI registry entry for CC:CF:FE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
