Bouffalo Lab's MAC footprint spans two IEEE entities that should be aliased to one maker: "Bouffalo Lab (Nanjing) Co., Ltd." (23 blocks, about 385.9 million addresses) and "Hong Kong Bouffalo Lab Limited" (3 blocks, about 50.3 million) — a combined ~26 blocks and a large, fast-growing footprint, not a negative finding. Verified Nanjing samples include 7C:B9:4C, FC:13:F0, AC:D8:29, C4:D7:FD, B8:3D:FB, and 28:BB:ED, plus 24:94:94 and B4:E8:42 for the Hong Kong entity. The Nanjing entity is registered at 5F, Gongxiang Space, No.100 Tuanjie Road, Nanjing, China, and the Hong Kong entity at Lee Garden One, Causeway Bay, Hong Kong. These OUIs appear on RISC-V Wi-Fi/BLE/Zigbee/Thread connectivity SoCs (BL602, BL616, BL808, etc.) — common in budget smart-home devices, IoT modules, and Wi-Fi peripherals. Bouffalo is a RISC-V Wi-Fi competitor to Espressif, common in Tuya-ecosystem and white-label smart-home gear (cross-references the existing Tuya, Espressif, Beken, and Telink entries). The key analyst point is the chipset pattern: a Bouffalo Lab OUI identifies a device built on Bouffalo RISC-V Wi-Fi/BLE silicon regardless of brand. For triage, that's most often a budget smart-home/IoT device or Wi-Fi peripheral — the brand on the box is unknown from the OUI.

- Special note
- NOT a negative finding — ~26 blocks across two entities, registering new blocks rapidly. Chipset-OUI case. RISC-V Wi-Fi competitor to Espressif; common in Tuya-ecosystem/white-label smart-home gear. Alias the two entities. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
- Related vendors
- Espressif (RISC-V Wi-Fi competitor); smart-home ecosystem cross-reference — Tuya, Beken, Telink
- Analyst note
- A Bouffalo Lab OUI identifies a device built on Bouffalo RISC-V Wi-Fi/BLE silicon REGARDLESS of brand — most often a budget smart-home/IoT device or Wi-Fi peripheral, frequently white-label or Tuya-ecosystem. The brand on the box is unknown from the OUI.
