Shenzhen Yunlink Technology Co., Ltd — 2 prefixes (MA-L)
Summary
- // what this is
- Shenzhen Yunlink Technology is registered to MAC prefix
44:D1:FAand 1 more in the IEEE OUI database. When a device's MAC address begins with44:D1:FA, that block was registered by Shenzhen Yunlink Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Substantive vendor: 2 OUI blocks + live product catalog matching wireless-networking hardware expectations. No security advisories found (Unknown, not confirmed clean).
About this vendor.
Shenzhen Yunlink Technology Co., Ltd holds two IEEE MA-L (24-bit) OUI blocks — 44:D1:FA and 7C:27:3C — both registered to the identical org name and Shenzhen, Guangdong address, which rules out a bare single-block shell registration. The company trades publicly as "Yuncore," operating live corporate sites (yuncore.com, yunlink.net) plus storefronts on Made-in-China and Alibaba and company pages on LinkedIn and Facebook, giving independent, non-registry corroboration that this is a real, identifiable manufacturer rather than a dormant OUI holder. Yuncore's marketed product line — indoor/outdoor Wi-Fi access points, outdoor CPE, LTE/4G/5G routers, PoE switches, WLAN/AC controllers, point-to-point/point-to-multipoint wireless bridges, and adjacent IoT gear such as IP cameras and in-vehicle Wi-Fi — is consistent with a wireless-networking-hardware OUI, corroborating the registry facts from an independent (device-category) angle. A same-name-adjacent but legally distinct IEEE registrant, "HONGKONG YUNLINK TECHNOLOGY LIMITED" (OUI 78:D3:8D), exists in the same registry snapshot and was deliberately excluded from this entry pending confirmation of any corporate relationship. No CVEs or security advisories tied to the Yuncore brand were found in this pass; that gap is recorded as Unknown, not as a clean bill of health. As with all IEEE OUI data, no registration date is published for either block, so none is recorded here.
