Shenzhen Bilian Electronic Co., Ltd. holds 40 MA-L blocks in the cached IEEE registry, all registered to the same Shenzhen, Guangdong address and trading under the brand LB-LINK. The company is a prolific Chinese OEM of wireless networking hardware: Wi-Fi modules (2.4/5 GHz, Wi-Fi 6/6E/7), Bluetooth and combo modules, USB Wi-Fi adapters, PCIe network cards, consumer routers, and IoT/smart-home radios. This breadth — and the fact that its modules are embedded inside other makers' devices — is why Bilian's OUI turns up so often on home and office Wi-Fi scans: the device you see is usually a phone, smart-home gadget, or laptop carrying a Bilian radio, not a standalone Bilian-branded box. Consolidating all 40 blocks into one vendor entry is far more useful than minting 40 near-identical per-prefix pages. Two data-quality notes matter here. First, the registry is internally inconsistent on this org: the name appears both as "SHENZHEN BILIAN ELECTRONIC CO.,LTD" and "Shenzhen Bilian electronic CO.,LTD", and the address carries postal code 518000 on most rows but 518110 on a handful, with a mojibake "?" replacing a full-width comma in the street field on several rows — all IEEE source-data artifacts, not lookup errors. Second, no registration dates exist: IEEE publishes none, and any "date registered" on third-party tools is a database artifact. On the security side, three Critical (CVSS 9.8) CVEs were disclosed in 2024 against the LB-LINK BL-W1210M v2.0 consumer router (plaintext credential storage, an unauthenticated root shell over UART, and admin-page clickjacking) — the most concrete risk signal found; apply the latest firmware. No CVEs were confirmed against the module product lines.
- IEEE assignment
- 40 prefixes → SHENZHEN BILIAN ELECTRONIC CO.,LTD, Shenzhen, Guangdong, CN [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- Registry / block size
- MA-L (24-bit OUI); 40 IEEE prefixes (~16.7M addresses each) in the cached oui.csv [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv). NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.
- MA-M / MA-S
- none — no MA-M (mam.csv) or MA-S (oui36.csv) block for Shenzhen Bilian. The single "bilian" hit in mam.csv is a DIFFERENT company, "Nanjing bilian information Technology Co.,Ltd." (8C147D4, Nanjing, Jiangsu) — do not conflate. [Confirmed] — enrichment/registries/mam.csv, enrichment/registries/oui36.csv
- Org name (registry)
- "SHENZHEN BILIAN ELECTRONIC CO.,LTD" on most rows; also rendered "Shenzhen Bilian electronic CO.,LTD" on later rows — IEEE source-data inconsistency [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- HQ / country
- NO.268, Fuqian Rd, Jutang community, Guanlan Town, Longhua New district, Shenzhen, Guangdong, CN (registry postal code 518000 on most rows, 518110 on some; several rows show a "?" mojibake artifact for a full-width comma) [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- Brand / trading name
- LB-LINK [Confirmed] — lb-link.com, lb-link.en.made-in-china.com
- Company website
- https://www.lb-link.com/ (live; confirms product portfolio) [Confirmed] — lb-link.com
- Company status
- active [Confirmed] — lb-link.com
- Device types
- Wi-Fi modules (2.4/5 GHz, Wi-Fi 6/6E/7), Bluetooth & combo modules, USB Wi-Fi adapters, PCIe network adapters, consumer routers, IoT/smart-home modules, sub-1 GHz / Zigbee modules, Cat.1bis cellular modules, drone long-range video-TX modules [Confirmed] — lb-link.com, lb-link.en.made-in-china.com
- OEM embedding
- Bilian/LB-LINK radio modules are embedded into third-party devices; multiple third-party sources state these include Samsung smartphones [Likely — single-source-cluster, third-party] — routerctrl.com
- Why it appears on your network
- the Bilian OUI shows up on Wi-Fi scans because its modules sit inside other makers' phones, smart-home gear, and laptops — the device is usually not a standalone Bilian product [Likely] — routerctrl.com
- Security note (W1 angle)
- three Critical CVSS-9.8 CVEs vs LB-LINK BL-W1210M v2.0 router (2024): CVE-2024-33375 (plaintext credential storage, CWE-256), CVE-2024-33374 (unauthenticated root shell via UART), CVE-2024-33377 (admin login-page clickjacking). Mitigation: apply latest firmware. No CVEs found against the module lines in this pass. [Confirmed for the three CVEs] — nvd.nist.gov (CVE-2024-33375 / -33374 / -33377), redfoxsecurity.medium.com
- Registration date
- Unknown — IEEE publishes none; third-party "date registered" values are database artifacts [Confirmed] — IEEE does not publish OUI dates
- Verified sample prefixes (all MA-L)
- 203233, 0C8C24, 10A4BE, CC641A, 145D34 [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- Analyst note
- A globally-administered Bilian OUI identifies a device carrying a Bilian/LB-LINK radio — frequently an embedded module rather than a branded router. The most actionable security item is the BL-W1210M v2.0 CVE cluster; treat budget consumer routers in this segment as patch-and-credential risks generally.
