Govee's IEEE registrant is "Shenzhen Intellirocks Tech. Co. Ltd." — the maker of the Govee brand — which holds 2 MA-L blocks, D4:13:68 and D4:AD:FC, registered at No. 3301, Block C, Section 1, Chuangzhi Yuncheng Building, Liuxian Avenue, Xili, Nanshan District, Shenzhen, China. These OUIs appear on smart LED light strips and bulbs, Wi-Fi/Bluetooth lighting, temperature and humidity sensors, and some appliances. The corporate structure splits the names: "Govee" is Govee Moments Trading Limited (a Hong Kong sales entity), while "Intellirocks" (Shenzhen Intellirocks Tech Co., Ltd.) is the IEEE registrant — confirmed via Govee's own privacy policy. The key analyst point is that despite holding 2 own-name OUIs, many Govee Wi-Fi devices surface under their Wi-Fi/BLE chipset vendor's OUI (for example Espressif, already covered) rather than the Intellirocks OUI. For triage, a D4:13:68 or D4:AD:FC OUI indicates a Govee/Intellirocks device, but absence of that OUI doesn't rule out Govee — check for Espressif and other chipset OUIs too.
