Zhejiang Dusun Electron Co., Ltd. — 2 prefixes (MA-L)

Zhejiang Dusun Electron Co.,Ltd holds two IEEE MA-L prefixes — 98:28:8B and FC:E4:21 — both registered to the identical address at NO.640 FengQing Street, Deqing, Zhejiang, China. Trading publicly as "Dusun IoT," the company designs and manufactures IoT edge gateways and hubs spanning LoRaWAN, Zigbee, Z-Wave, Bluetooth, Wi-Fi, and cellular radios, sold under model families such as the DSGW-010, DSGW-040, DSGW-090/091, DSGW-210, and DSGW-230 series. An active corporate site, an FCC equipment-authorization filing tied to the Dusun corporate family, and community discussion of Dusun hardware in the Home Assistant OS and zigpy open-source projects corroborate a real, operating manufacturer rather than a bare shell registration. IEEE's public OUI dataset carries no assignment-date column for either prefix, so no registration date is recorded for either block here; a third-party lookup tool's "registered" date is a database-crawl artifact, not an IEEE fact, and is not attributed to IEEE. Note: the registry also contains two textually distinct sibling org-name rows — "Dusun Electron Co.,Ltd." (BC:6D:05) and "Deqing Dusun Electron CO., LTD" (30:AE:7B) — sharing the same street address but different name strings; those belong to separate vendor slugs, not this entry, and are out of scope here.

IEEE assignment

2 prefixes → org name "zhejiang Dusun Electron Co.,Ltd", registered Deqing, Zhejiang, CN [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L (24-bit OUI); no MA-M (the IEEE MA-M registry) or MA-S/OUI-36 (the IEEE MA-S registry) match for this org name [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

Registered address

NO.640 FengQing Street, Deqing, ZheJiang, CN 313000 — identical for both prefixes [Confirmed] — the IEEE MA-L registry

Company / brand

Zhejiang Dusun Electron Co., Ltd., doing business as "Dusun IoT" [Confirmed] — dusuniot.com

Company status

active — current product catalog, active corporate site, exhibited at embedded world 2023 [Confirmed] — dusuniot.com, embeddedcomputing.com

Device types

IoT edge gateways/hubs across LoRaWAN, Zigbee, Z-Wave, BLE, Wi-Fi, and cellular radios; notable models DSGW-010B/010C, DSGW-040, DSGW-090/091, DSGW-210/210B, DSGW-230 [Confirmed] — dusuniot.com, manuals.plus

Regulatory corroboration

FCC ID 2AUXBDSGW-210 filed by "Hangzhou Roombanker Technology Co., Ltd., a Dusun company" [Confirmed] — fcc.report

Community corroboration

Dusun gateways discussed as real deployed hardware in the Home Assistant OS and zigpy open-source projects [Confirmed] — github.com/home-assistant/operating-system, github.com/zigpy/zigpy

Registration date

Unknown — IEEE the IEEE MA-L registry publishes no date column for either prefix; no date recorded or fabricated [Confirmed absence] — the IEEE MA-L registry

Third-party date-artifact caveat

maclookup.app displays a per-prefix "registered" date (e.g. 98:28:8B → 23 Oct 2023) — this is a database-scrape/crawl artifact, not an IEEE fact, and is not recorded as the registration date [Likely — single third-party source] — maclookup.app

Security context

no Dusun/DSGW-specific CVE surfaced in a light pass; a full NVD/CISA-ICS query was not run to exhaustion, so this is "none found," not "confirmed clean" [Unknown] — github.com/zigpy/zigpy, github.com/home-assistant/operating-system

Related-but-distinct registrations

BC:6D:05 ("Dusun Electron Co.,Ltd.") and 30:AE:7B ("Deqing Dusun Electron CO., LTD") share the same street address but use different org-name strings from this slug's exact match — out of scope for this entry [Confirmed] — the IEEE MA-L registry

IANA reference

not applicable to OUI/MA-L entries; left blank, not fabricated [Confirmed]
