OUI 1C:47:F6 is a single MA-L (24-bit, large block, ~16.8M addresses) assignment registered to "Zhidao Network Technology(Shenzhen) Co.,Ltd" at B3, 11/F, Exiang Technology Building, No. 31, Zhongsi Road, Gaoxin, Maling Community, Yuehai Street, Nanshan District, Shenzhen, CN 518000. This is the company's only IEEE block — no additional assignments appear in the MA-L, MA-M, or MA-S registries. A naming-collision caveat dominates any work on this prefix: at least two unrelated companies share the "Zhidao Network Technology" name and must not be conflated. The Shenzhen entity tied to this OUI is associated with the autonomous-driving / vehicle-to-everything (V2X) ecosystem — roadside units (RSU), on-board units (OBU), and intelligent-transportation-system (ITS) infrastructure hardware, with the broader Zhidao Wanglian / "Mushroom Chelian" platform backed by Tencent and JD.com. A separate firm, Quanzhou Zhidao Network Technology Co., Ltd., trades in footwear and consumer goods (the ZIITOP trademark) and is NOT the OUI holder. No CVEs or vendor-specific vulnerability disclosures were found for this prefix or vendor; any V2X/ITS security concern is a category-level consideration, not a documented finding here. As with every IEEE OUI, no registration date is published — a "2021-12-30" date on a third-party lookup is a database artifact, not an IEEE fact.
- IEEE assignment
- 1C:47:F6 → Zhidao Network Technology(Shenzhen) Co.,Ltd [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv), corroborated by maclookup.app
- Registry / block size
- MA-L (24-bit OUI, ~16.8M addresses) [Confirmed] — IEEE MA-L registry; maclookup.app
- Registered address
- B3, 11/F, Exiang Technology Building, No. 31, Zhongsi Road, Gaoxin, Maling Community, Yuehai Street, Nanshan District, Shenzhen, CN 518000 [Confirmed] — IEEE MA-L
- HQ / country
- Shenzhen, Guangdong, CN [Confirmed] — IEEE MA-L
- Additional assignments
- none — single MA-L block; no entries in MA-M or MA-S for this org (the mam.csv "Sizhidao" hit is an unrelated street name in another company's address) [Confirmed] — IEEE oui.csv / mam.csv / oui36.csv
- Registration date
- not published by IEEE; a third-party "2021-12-30" appears on maclookup.app but is a database artifact, NOT an IEEE assignment date and must not be attributed to IEEE [Unknown] — IEEE oui.csv carries no date column; maclookup.app (artifact only)
- Device types
- V2X / autonomous-connected-vehicle hardware — roadside units (RSU), on-board units (OBU), and ITS infrastructure; embedded network adapters in those units. Not consumer networking gear (no routers/switches/APs). [Likely] — cbinsights.com, infrapppworld.com, bloomberg.com (two-angle web corroboration; vendor does not self-publish a product spec page)
- Company status / profile
- associated with the Zhidao Wanglian / "Mushroom Chelian" autonomous-driving and vehicle-road-coordination platform; reporting cites Tencent and JD.com backing and autonomous-bus pilots (Singapore consortium). [Likely] — bloomberg.com, infrapppworld.com, cbinsights.com
- Vendor website
- not confirmed — no public product/company website verifiable for the Shenzhen OUI registrant in English-language search results [Unknown] — no source
- Entity disambiguation
- "Zhidao Network Technology (Shenzhen) Co., Ltd." (this OUI; V2X/autonomous vehicles) is DISTINCT from "Quanzhou Zhidao Network Technology Co., Ltd." (footwear/consumer goods, ZIITOP trademark, NOT the OUI holder). [Confirmed] — maclookup.app, importgenius.com, trademarks.justia.com
- Security context
- no CVEs or public advisories found for this vendor/OUI in NVD or CVE.org. V2X/ITS road-infrastructure hardware carries class-level risk (high-value targets for traffic-disruption attacks), but this is a category note, not a vendor-specific finding. [Likely] — nvd.nist.gov, cve.org (searched; no vendor-specific hits)
- Analyst note
- a 1C:47:F6 globally-administered address identifies genuine Zhidao(Shenzhen) hardware, but verify device class before assuming consumer networking — this is V2X/ITS infrastructure, not a router/AP vendor. Do not associate this OUI with the unrelated Quanzhou footwear company.
