Hui Zhou Gaoshengda Technology Co., Ltd holds 54 MA-L blocks in the IEEE registry, all registered as "Hui Zhou Gaoshengda Technology Co.,LTD" in Huizhou, Guangdong, China. The blocks split across two registered addresses — most carry No.2, Jin-da Road, Huinan Industrial Park (postal 516025), and a later batch carries No.75, Zhongkai High-Tech Development District (postal 516006). Verified samples include E0:01:C7, 84:C8:A0, 84:3E:1D, A8:16:9D, 38:C8:04, and 64:E0:03. Gaoshengda is a Chinese OEM/ODM that builds embedded Wi-Fi and Wi-Fi+Bluetooth combo modules (FCC grantee 2AC23) sold as white-label components to other brands, so its name rarely appears on consumer packaging. These modules end up inside home routers, smart-home gear (cameras, sensors, switches), remote controls, and IoT appliances. The practical consequence for triage matches AzureWave or Espressif: a Gaoshengda OUI identifies a Gaoshengda Wi-Fi/BT module, not a Gaoshengda-branded device. Seeing one in DHCP or switch tables means "an unrecognized white-label IoT/Wi-Fi module is present" — the host could be any brand — so it is useful for module-level fingerprinting, not brand attribution, and is not inherently a rogue-device signal. No CVEs are attributed to Gaoshengda in NVD or MITRE; security posture depends on the integrating brand's firmware, not on Gaoshengda directly.

- Registration date
- Unknown — IEEE publishes no assignment/registration dates in its OUI data. Any "date registered" (e.g., the "05 October 2012" shown on maclookup.app) is a third-party database artifact, not an IEEE fact, and must not be attributed to IEEE [Confirmed] — IEEE oui.csv columns (Registry, Assignment, Organization Name, Organization Address)
- Security context
- no CVEs attributed to Gaoshengda in NVD or MITRE CVE (searched June 2026). General white-label IoT firmware risks apply (shared SoCs, weak default credentials) but are upstream/integrator-dependent, not Gaoshengda-specific [Confirmed] — https://nvd.nist.gov/vuln/search/results?query=gaoshengda&results_type=overview&form_type=Basic&search_type=all
- Related vendors
- none significant (module supplier to many brands; same "module, not device brand" pattern as AzureWave, Espressif, Tuya)
- Analyst note
- a Gaoshengda OUI in DHCP/switch tables means "a Gaoshengda Wi-Fi/BT module is present" — the host device could be any brand. Use for module-level fingerprinting, not brand attribution; an unexpected Gaoshengda OUI usually indicates an unrecognized white-label IoT device, not inherently a rogue one.
