Visteon Corporation is an American automotive electronics supplier, spun off from Ford Motor Company in 2000 and now focused exclusively on vehicle cockpit electronics after divesting its climate and interiors businesses in 2015-2016. It trades on Nasdaq as VC. Across the IEEE registry the Visteon group holds twelve assignments: ten MA-L (OUI-24) blocks, one MA-M, and one MA-S. Seven MA-L blocks are registered directly to "Visteon Corporation" (00-09-93, A8-40-0B, F8-55-CD, 00-0A-30, 0C-D9-C1, FC-35-E6, 7C-FC-3C), with the remaining allocations registered to subsidiaries and joint ventures: Yanfeng Visteon Electronics Technology (Shanghai) holds F0-65-C2, YanFeng Visteon (ChongQing) Automotive Electronic holds 4C-53-69, and Visteon Portuguesa holds D0-B2-70; Shanghai Visteon Automotive Electronics System holds the MA-M block (2C-48-35-B), and Changchun FAW Yanfeng Visteon Automotive Electronics holds the MA-S block (70-B3-D5-93-B). The directly-held blocks sit on Visteon's Van Buren Township, Michigan campus (One Village Center Drive, 48111); one older record gives the adjacent address string "Belleville, MI 48111" for the same campus. The device population behind these OUIs is automotive embedded ECUs — cockpit domain controllers (the SmartCore line), Android-based in-vehicle infotainment head units, digital instrument clusters, and connected-services/telematics modules — not consumer or enterprise networking gear. The practical consequence for OUI lookup: a Visteon-prefixed MAC observed on a network most likely belongs to a vehicle's infotainment or telematics ECU reached over in-vehicle Ethernet, a workshop diagnostic interface, or a tethered hotspot. Seeing one on a corporate or home network is unusual and worth a second look — it may indicate a vehicle tethered over USB or a mechanic's diagnostic laptop bridging a vehicle interface.
- IEEE assignment
- 12 blocks — 10 MA-L, 1 MA-M, 1 MA-S — across Visteon Corporation and its subsidiaries/JVs [Confirmed] — IEEE registry (cached CSVs at enrichment/registries/), corroborated by maclookup.app for 7C:FC:3C and FC:35:E6
- Registry / block size
- MA-L (24-bit OUI, ~16.7M addresses each), MA-M (28-bit), MA-S (36-bit) [Confirmed] — IEEE registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools (e.g. maclookup.app shows "April 27, 2016" for 7C:FC:3C and "March 28, 2013" for FC:35:E6) is a database artifact, not an IEEE fact.

- HQ / country
- One Village Center Drive, Van Buren Township, MI 48111, US (registry address on directly-held blocks; one older record gives "Belleville, MI 48111" — adjacent address string for the same campus) [Confirmed] — IEEE registry, maclookup.app, en.wikipedia.org/wiki/Visteon
- Company status
- active; publicly traded (Nasdaq: VC); founded 2000 as a Ford spin-off [Confirmed] — visteon.com, en.wikipedia.org/wiki/Visteon
- Device types
- cockpit domain controllers (SmartCore, Qualcomm-SoC-based), Android in-vehicle infotainment head units (Bluetooth/USB/CarPlay/Android Auto), digital instrument clusters, telematics / connected-services modules [Confirmed] — visteon.com product pages, prnewswire.com SmartCore release

- Subsidiary / JV prefixes
- F0:65:C2 (Yanfeng Visteon Electronics, Shanghai), 4C:53:69 (YanFeng Visteon ChongQing), D0:B2:70 (Visteon Portuguesa), 2C:48:35:B (MA-M; Shanghai Visteon Automotive Electronics System), 70:B3:D5:93:B (MA-S; Changchun FAW Yanfeng Visteon) [Confirmed] — IEEE registry (cached CSVs)
- Security context
- connected automotive products are automotive-grade OT/ECU attack surface, not IT networking gear. Visteon publishes a layered product-security posture (hardware security modules, secure boot, PKI-authenticated ECU software, one-time-programmable manufacturing fuses, dual-copy OTA updates). Bluetooth and USB are confirmed in product materials; Wi-Fi/cellular are implied by connected-services and OTA capability but not explicitly named on the public cybersecurity page. No Visteon-specific CVE surfaced in NVD/CVEdetails in this pass; automotive IVI broadly is an active research target [Likely] — visteon.com/technology/cybersecurity, vicone.com automotive cybersecurity report
- Network context for OUI lookup
- a Visteon-prefixed MAC most likely originates from an automotive ECU (infotainment head unit, domain controller, or telematics module) on in-vehicle Ethernet, a workshop diagnostic link, or a vehicle-tethered hotspot; not general-purpose networking equipment. On a home/corporate network it is an anomaly — possibly a USB-tethered vehicle or a diagnostic laptop [Likely] — visteon.com cockpit domain controller page, maclookup.app
- Registration date
- none published — IEEE OUI data has no date column; third-party "date registered" values are ingestion artifacts and must not be cited as IEEE facts [Unknown] — standards.ieee.org/products-programs/regauth
- Analyst note
- a Visteon OUI on a globally-administered address reliably identifies Visteon-group automotive hardware; the JV/subsidiary blocks (Yanfeng/Shanghai/ChongQing/Changchun) point to China-built units, while the directly-held blocks map to the Michigan campus.
