FN-Link Technology is a Chinese wireless-module manufacturer whose IEEE allocations span three closely related registered names — FN-LINK TECHNOLOGY LIMITED, FN-LINK TECHNOLOGY Ltd., and HUNAN FN-LINK TECHNOLOGY LIMITED — that together hold 52 MA-L blocks. The registry addresses split between Shenzhen (Bao'an District, Guangdong) and Changsha (Liuyang Economic & Technical Development Zone, Hunan), which is why consolidating all three variants into one vendor entry is more useful than minting near-identical per-name pages. The company sells embedded Wi-Fi and Bluetooth/BLE modules as OEM components rather than finished consumer products, so an FN-Link OUI on a network almost always indicates a wireless module integrated inside another brand's device — a laptop, tablet, smart-TV, IP camera, smart plug, or AI speaker — not a device sold under the FN-Link name. That OEM model is the key analyst caveat: identifying the OUI tells you which module is inside the box, but the visible brand on the box is someone else's. The large block count (52 MA-L allocations, roughly 870 million addresses) is consistent with the company's stated high-volume module production. IEEE publishes no registration date for any of these blocks; any "date registered" shown by third-party lookup tools is a database artifact, not an IEEE fact.
- IEEE assignment
- 52 MA-L prefixes across three name variants — FN-LINK TECHNOLOGY LIMITED, FN-LINK TECHNOLOGY Ltd., HUNAN FN-LINK TECHNOLOGY LIMITED [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- Registry / block size
- MA-L (24-bit OUI); 52 IEEE prefixes (~872M addresses). 0 entries in MA-M (mam.csv) or MA-S (oui36.csv). NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools (maclookup.app, Wireshark OUI DB) is a database artifact, not an IEEE fact. [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv, mam.csv, oui36.csv)
- HQ / country
- CN (China). Two registry addresses appear: Shenzhen — A Building, HuiXin industrial park, No 31, YongHe road, Fuyong town, Bao'an District, Shenzhen, Guangdong 518100 (and a second Bao'an address, 5th Floor, A Building, Haoye Logistics Park, Shugang Channel, 518000); Hunan — No.8, Litong Road, Liuyang Economic & Technical Development Zone, Changsha, Hunan (postcode variants 410329/410300) [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- Company status
- active [Confirmed] — fn-link.com (https://www.fn-link.com/)
- Device types
- embedded Wi-Fi (802.11 a/b/g/n/ac/ax) and Bluetooth/BLE modules sold as OEM components; also Zigbee, Sub-1GHz, Cat.1bis cellular, PLC, and AIoT modules. Modules are integrated into laptops, tablets, smart TVs/set-top boxes, IoT/smart-home devices (smart bulbs, plugs, switches), IP cameras, AI speakers, USB Wi-Fi dongles, and development boards. An FN-Link OUI almost always indicates an OEM module inside another brand's product, not a device sold under the FN-Link name. [Confirmed] — fn-link.com/products.html, fn-link.en.made-in-china.com
- Founding year
- 2015 (per the vendor's own company profile) [Likely] — fn-link.com/company-profile.html (single-source, vendor self-reported)
- Notable customers/products
- company materials and trade listings cite OEM customers including Huawei, Xiaomi, Haier, Midea, Hisense, Gree, Hikvision, Skyworth, and Ecovacs [Likely] — fn-link.com/company-profile.html, fn-link.en.made-in-china.com (vendor self-reported; not independently audited)
- Verified sample prefixes (all MA-L)
- D4:8A:3B (HUNAN FN-LINK), 48:D8:90 (FN-LINK TECHNOLOGY LIMITED / Shenzhen), 88:83:5D (FN-LINK TECHNOLOGY LIMITED / Hunan), A0:F4:59 (FN-LINK TECHNOLOGY LIMITED / Shenzhen Haoye), 40:80:E1 (FN-LINK TECHNOLOGY Ltd. / Hunan) [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- Registration date
- Unknown — IEEE publishes no OUI registration dates. Third-party tools display values such as "20 June 2013" or "updated 17 November 2020"; these are database artifacts of the third-party service, not IEEE facts, and must not be cited as an IEEE registration date. [Confirmed null] — no IEEE source
- Security context
- No CVEs specific to FN-Link modules were found in the NVD (searched June 2026). Absence of named CVEs does not imply the modules are vulnerability-free — security research is typically published against the finished-product brand (e.g. a Hikvision camera or Xiaomi smart plug) rather than the OEM module supplier. Standard IoT hygiene applies: segment IoT devices onto an isolated/guest VLAN, enforce WPA2/WPA3, change default credentials, monitor for unexpected traffic. No sanctions listing or threat-intelligence reporting specific to FN-Link was found. [Confirmed null on CVEs] — nvd.nist.gov/vuln/search
- IANA reference
- Unknown — no IANA RFC reference applicable to this OUI entry (blank stays blank). [Confirmed null]
- Analyst note
- An FN-Link OUI on a globally-administered address identifies an FN-Link wireless module, but that module is almost always embedded inside another vendor's product — so the OUI tells you the module maker, not the device brand. The three name variants are one corporate family; treat them as a single vendor for inventory and classification.
