MAC address vendor

Chengdu Xuguang Technology Co., Ltd. — 2 prefixes (MA-L)

Primary prefix
9C:44:3D
Block
MA-L
Status
Active

Summary

// what this is
Chengdu Xuguang Technology is registered to MAC prefix 9C:44:3D and 1 more in the IEEE OUI database. When a device's MAC address begins with 9C:44:3D, that block was registered by Chengdu Xuguang Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Real, identifiable manufacturer with device-level and multi-prefix corroboration, not a paper registration.

About this vendor.

Updated  ·  Confidence: Medium

Chengdu Xuguang Technology Co., Ltd. (成都旭光科技) is a Sichuan-based electronics manufacturer holding two confirmed IEEE MA-L OUI assignments — 9C:44:3D and 74:22:0D — both registered to the same Chengdu address on Park Road. Unlike a bare single-OUI shell registration, this vendor shows verifiable product substance: an FCC equipment authorization (FCC ID 2BCHJXGMW-10) for a smart switch model XGMW-10, filed September 2023, and a broader catalog spanning RF components (50 MHz–5 GHz), electronic tuners, and WiFi/MCU control modules built on Realtek, Qualcomm, and MediaTek chipsets for video, data-communication, and mobile-communication devices. Independent trade and company-data sources — Bloomberg, PatSnap, Sourceready, and the company's own Alibaba supplier storefront — corroborate a functioning manufacturer rather than a paper registration. No security incidents, vulnerabilities, or botnet activity have been publicly attributed to this vendor or its devices; unrelated Chengdu-based threat actors that surfaced in general search (e.g. Integrity Technology Group/Flax Typhoon, Sichuan Silence) are distinct entities and must not be conflated with this OUI holder. IEEE's public the IEEE MA-L registry publishes no assignment date for either prefix, consistent with IEEE's standard non-dated registry format — no date is recorded here, and none should be fabricated or borrowed from third-party "date registered" scrapes.

Analyst note
two independent MA-L blocks plus a named, dated FCC-certified consumer device and a coherent module/component product line together clear the abstain-on-shells bar — this is a real, identifiable manufacturer, not a bare registration.
