Xiaomi's MAC footprint is spread across at least four IEEE registrants, so a single "Xiaomi" picture requires aggregating them: "Xiaomi Communications Co Ltd" (the largest, ~229 blocks), "Beijing Xiaomi Mobile Software Co., Ltd" (~68), "Beijing Xiaomi Electronics Co., Ltd." (~20), and "XIAOMI Electronics,CO.,LTD" (~8) — well over 300 combined. All are based in Beijing's Haidian District. These OUIs span smartphones (Mi, Redmi, POCO), an enormous IoT/smart-home range (the Mi Home ecosystem: plugs, sensors, cameras, vacuums, lights), routers, wearables, and TVs — which is why Xiaomi OUIs are extremely common in smart-home environments. Xiaomi Android phones use MAC randomization. For triage, multiple Xiaomi OUIs appearing at once usually means a cluster of smart-home gadgets; in enterprise contexts these are unmanaged IoT/shadow-IT with cloud connectivity (often to Chinese endpoints), which is frequently a policy and segmentation concern.
