Zhejiang Tmall Technology Co., Ltd. holds 19 MA-L (24-bit OUI) blocks in the IEEE registry, all registered to the same legal entity but split across two addresses: one in Hangzhou (No.969 Wenyi West Road, Yuhang District — the canonical Alibaba campus seat) and one in Shenzhen (Ali Center, No.3331 Keyuan South Road, Nanshan District). The company is a consolidated subsidiary of Alibaba Group Holding Limited, named as a significant subsidiary in Alibaba's SEC Form 20-F filings across multiple fiscal years. In practice these prefixes front the Tmall Genie (天猫精灵) hardware line — Alibaba's AliGenie-powered smart speakers, smart displays, and related smart-home IoT devices, launched July 2017 as a domestic competitor to Amazon Echo and Google Home. Because consolidating one vendor entry beats minting 19 near-identical per-prefix pages, the useful framing is: a globally-administered prefix in this set identifies Alibaba/Tmall Genie consumer IoT hardware, mostly sold inside China. Two caveats matter for any work here. First, device-type attribution to this specific OUI block is inferred from the corporate family — IEEE publishes no device-type annotation, and individual product SKUs are often manufactured by sibling Zhejiang entities (e.g. Zhejiang Weilai Jingling AI Technology for the X6) even when Zhejiang Tmall Technology is the registrant. Second, IEEE publishes no assignment dates for OUI/MA-L records, so any "date registered" shown by third-party MAC databases is a database artifact, not an IEEE fact, and no date is recorded here.
- IEEE assignment
- 19 prefixes → Zhejiang Tmall Technology Co., Ltd. [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv); cross-confirmed hwaddress.com, udger.com
- Registry / block size
- MA-L (24-bit OUI); holds 19 IEEE prefixes; no entries in MA-M (mam.csv) or MA-S (oui36.csv) [Confirmed] — IEEE oui.csv. macaddress.io's statistics page references ~20 registrations; exact count may differ by database snapshot. NOTE: IEEE public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.
- Registered addresses
- (1) No.969 Wenyi West Road, Wuchang Street, Yuhang District, Hangzhou, Zhejiang, CN 310024; (2) Ali Center, No.3331 Keyuan South RD (Shenzhen Bay), Nanshan District, Shenzhen, Guangdong, CN 518000 [Confirmed] — IEEE oui.csv. Both are Alibaba Group campus addresses used for OUI registration, not necessarily the statutory Zhejiang registration seat. [Likely on which is statutory] — hwaddress.com, dnb.com
- Country
- People's Republic of China (Zhejiang / Guangdong) [Confirmed] — IEEE oui.csv
- Parent entity
- Alibaba Group Holding Limited; listed as a significant / consolidated subsidiary in Alibaba SEC Form 20-F filings (FY2017–FY2026) [Confirmed] — sec.gov 20-F exhibit 8.1 (2019, 2026 filings)
- Company status
- active [Likely] — Alibaba SEC filings list it as a current consolidated entity; no dedicated company status registry checked this pass
- Device types
- Tmall Genie (天猫精灵) AI smart speakers, smart displays (CC series, 4"–10" screens), voice-controlled home-automation hubs, and related peripherals (smart mirrors / QUEEN line, portable speakers, tablets); AliGenie voice assistant; launched July 2017 [Likely] — attribution inferred from corporate family, not an IEEE device-type field — en.wikipedia.org/wiki/Tmall_Genie, baike.baidu.com, ifdesign.com
- Connectivity
- Wi-Fi 2.4 GHz + Bluetooth 4.0 confirmed for base Tmall Genie smart-speaker models; later/newer models likely add 5 GHz Wi-Fi and newer Bluetooth, but per-model specs not source-confirmed this pass [Confirmed on base model; Likely otherwise] — en.wikipedia.org/wiki/Tmall_Genie
- Related vendors
- sibling Zhejiang Alibaba subsidiaries manufacture individual SKUs (e.g. Zhejiang Weilai Jingling AI Technology Co. for the X6 model) [Likely] — ifdesign.com
- Vendor site
- no dedicated hardware-brand site for the legal entity; consumer brand is Tmall Genie (genie.tmall.com, Chinese-language Alibaba storefront); corporate data via Alibaba investor relations / SEC filings [Likely] — baike.baidu.com, sec.gov
- Security context
- no product-specific CVEs or published exploits found this pass. Standard always-on Chinese-jurisdiction consumer-IoT risk profile: voice/usage telemetry processed on Alibaba Cloud servers in China under PRC law (2017 National Intelligence Law, PIPL); smart speakers prone to accidental activation / unintended audio capture; AliGenie reported on ~200M IoT devices by 2020 (broad surface); 2019 US Senate concern over Chinese-made smart devices collecting sensitive data [Likely] — sciencedirect.com, cassidy.senate.gov, alibabacloud.com
- Analyst note
- a globally-administered prefix in this set reliably identifies Alibaba/Tmall Genie consumer IoT hardware; treat data-handling as Chinese-jurisdiction (Alibaba Cloud, PIPL) for asset/risk classification. Device-type and per-model specs are inferential from corporate context, not IEEE-published.
