Which company owns MAC address prefix 80:F7:A6?

MAC address prefix 80:F7:A6 is registered to Shenzhen C-Data Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 80:F7:A6 has a network interface built by Shenzhen C-Data Technology Co., Ltd..

What is the OUI 80:F7:A6?

80:F7:A6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen C-Data Technology Co., Ltd.. It covers every address from 80:F7:A6:00:00:00 to 80:F7:A6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 80-F7-A6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:F7:A6:00:00:00 that is 80:F7:A6 — 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 Shenzhen C-Data Technology Co., Ltd. located?

Shenzhen C-Data Technology Co., Ltd. is listed at #201, Building A4, Nanshan Zhiyuan, No.1001, Xueyuan Avenue, Changyuan Community,Taoyuan,Nanshan Shenzhen Guangdong CN 518055 in the IEEE OUI registry entry for 80:F7:A6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
