Who owns the MAC starting with 1C:2F:A2?

The prefix 1C:2F:A2 is registered to Guangzhou Shiyuan Electronic Technology Company Limited. Any device whose MAC starts with 1C:2F:A2 (for example, 1C:2F:A2:1A:2B:3C) was made by this company.
What it means to see this device on your network
Knowing the manufacturer helps identify what is connected to your Wi-Fi or company network. A Guangzhou Shiyuan Electronic Technology Company Limited MAC you don't recognize could be a legitimate device (a phone, a TV, a camera) — or one that shouldn't be there. Guangzhou Shiyuan Electronic Technology Company Limited has 30 MAC prefixes registered with the IEEE (see others under "Read also").
