Xiaomi Electronics — 28 prefixes (MA-L)

The slug "vendor-xiaomi-electronics" consolidates three closely-related IEEE registry names belonging to the same Xiaomi sub-entity in Beijing: "Beijing Xiaomi Electronics Co., Ltd." (with period), "Beijing Xiaomi Electronics Co.,Ltd" (no period), and "XIAOMI Electronics,CO.,LTD" — together holding 28 MA-L (24-bit OUI) blocks. These are distinct from the larger Xiaomi group registrations such as "Xiaomi Communications Co Ltd" and "Beijing Xiaomi Mobile Software Co., Ltd," which hold their own MA-L blocks under separate vendor slugs, so treating this electronics entity as one consolidated page is more useful than minting per-prefix pages. All three name variants resolve to Beijing, China registry addresses (Xiaomi Campus / Xiaomi Building / QingHe Technology Park, Haidian District). The entity is a subsidiary of Xiaomi Corporation — the Beijing consumer-electronics maker founded in 2010 and listed on the Hong Kong Stock Exchange in 2018 — and its OUI blocks appear on consumer IoT and smart-home hardware: smartphones, tablets, routers, security cameras, smart lighting, sensors, wearables, and streaming devices. A standard OUI caveat applies: IEEE publishes no registration dates for MAC/OUI blocks, so any "first registered" date shown by third-party MAC databases (e.g. maclookup.app's 2016-04-27) is a database-ingestion artifact, not an IEEE-issued fact, and must not be recorded as an allocation date. Security context is supply-chain/telemetry-oriented rather than network-layer: Forescout's 2024 research found Xiaomi devices (categorized via this entity's OUI) present in US enterprise, government, and healthcare networks, and 20 software vulnerabilities were found and resolved via Xiaomi's HackerOne program — but no exploits are tied to the OUI assignment itself.

IEEE assignment

28 MA-L prefixes → registered under three Xiaomi name variants, all in Beijing, CN [Confirmed] — IEEE MA-L registry (regauth.standards.ieee.org)

Registry / block size

"Beijing Xiaomi Electronics Co., Ltd." (period), "Beijing Xiaomi Electronics Co.,Ltd" (no period), "XIAOMI Electronics,CO.,LTD" — same sub-entity [Confirmed] — IEEE MA-L registry; Forescout OUI enumeration

HQ / country

Beijing, China. Registry addresses: Xiaomi Campus (CN 100085); Xiaomi Building, No.68 Qinghe Middle St, Haidian District; Building C, QingHe ShunShiJiaYe Technology Park, #66 ZhuFang Rd, Haidian District [Confirmed] — IEEE MA-L registry

Parent company

Xiaomi Corporation, Beijing — founded April 2010, listed on Hong Kong Stock Exchange July 2018; this electronics entity is one of Xiaomi's many Chinese subsidiaries [Confirmed] — ir.mi.com company profile; companydata.com; Forescout

Company status

active [Confirmed] — mi.com / xiaomi.com

Device types

consumer IoT and smart-home — smartphones (Xiaomi/Redmi/POCO), tablets, laptops, routers, security cameras, smart lighting, sensors, wearables/fitness bands, streaming boxes, air purifiers. No public prefix-to-product mapping exists [Likely] — netify.ai; mi.com; maclookup.app

Allocation / registration date

Unknown — IEEE publishes NO registration date for OUI/MAC assignments. Third-party tools show "first registered 2016-04-27 / updated 2018-11-16"; these are database artifacts, NOT IEEE facts, and are not recorded as allocated_date

[Confirmed] — maclookup.app (artifact); IEEE the IEEE MA-L registry schema (no date column)

Security context

Forescout (2024) found Xiaomi devices (via this OUI) in US enterprise/government/healthcare networks; 20 software vulnerabilities found and resolved via Xiaomi HackerOne; Lithuanian NCSC raised data-privacy concerns on the Mi 10T 5G; Xiaomi publishes an ETSI EN 303 645 / OWASP-aligned IoT security baseline with BSI Kitemark. No CVEs tied to the OUI prefix itself

[Confirmed] — forescout.com; oversecured.com; everphone.com; hackerone.com/xiaomi

Analyst note

Risk is supply-chain/telemetry (cloud data flows), not network-layer OUI exploitation. Elevated scrutiny is reasonable in regulated/government networks given Chinese origin and IoT footprint; no malware campaigns tied to Xiaomi OUI prefixes confirmed in public threat-intel as of June 2026
