ADC Automotive Distance Control Systems GmbH — 3C:69:D1 (MA-L)

ADC Automotive Distance Control Systems GmbH holds a single IEEE MA-L block, 3C:69:D1, registered to an address in Lindau (Bodensee), Bavaria, Germany. Unlike a bare single-OUI shell, this registrant resolves to a substantial, identifiable company: German commercial-register records (Amtsgericht Kempten, HRB 6408) and a Legal Entity Identifier (52990053QKZNAT4DIV04) confirm it as an active legal entity, and independent corporate profiles (D&B, Bloomberg) and Continental AG's own materials describe it as a Continental division building distance-control and ADAS hardware — radar, camera, and lidar sensors and ECUs for assisted/automated driving. A December 2013 FCC equipment authorization filing (ELS 0050-EX-PL-2014) for an actual distance-control/ADAS device gives independent device-type corroboration that this OUI plausibly appears on in-vehicle networked sensor or ECU hardware, not merely a paperwork-only registration. One naming wrinkle: IEEE's own registry text and third-party aggregators both render the name with singular "System," while the company's legal filings use plural "Systems" — most likely a small transcription inconsistency carried from the original submission rather than two different entities, since address, industry, and OUI all line up to one registrant.

Registry / assignment

MA-L, 3C:69:D1 → "ADC Automotive Distance Control System GmbH" [Confirmed] — the IEEE MA-L registry line 24356

Registered address

Peter-Dornier-Strasse 10, Lindau, Bavaria, DE, 88131 [Confirmed] — the IEEE MA-L registry line 24356

Cross-registry check

no additional MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) blocks found under this or closely related names; appears to be a single-OUI assignment [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

Date registered

not recorded — IEEE's public OUI data (Registry, Assignment, Organization Name, Organization Address columns only) publishes no assignment/registration date; none fabricated or attributed to IEEE [Confirmed — absence is a registry design fact, not a gap] — the IEEE MA-L registry

Legal-name discrepancy

registry/aggregators show singular "ADC Automotive Distance Control System GmbH"; German commercial register and LEI record show plural "ADC Automotive Distance Control Systems GmbH" — treated as the same entity given matching address/industry, but the discrepancy is noted rather than silently resolved [Likely] — https://www.northdata.com/ADC%20Automotive%20Distance%20Control%20Systems%20GmbH,%20Lindau%20(Bodensee)/Amtsgericht%20Kempten%20HRB%206408, https://www.leikart.com/leicert/52990053QKZNAT4DIV4/

Company substance

active Continental AG division for ADAS (radar/camera/lidar sensors, ECUs, driving-assistance functions), headquartered in Lindau, Germany; corroborated by commercial-register, LEI, D&B, and Bloomberg records [Confirmed] — https://www.northdata.com/ADC%20Automotive%20Distance%20Control%20Systems%20GmbH,%20Lindau%20(Bodensee)/Amtsgericht%20Kempten%20HRB%206408, https://www.dnb.com/business-directory/company-profiles.adc_automotive_distance_control_systems_gmbh.34f7aefe8db63d1ff77733833fca56a6.html, https://www.bloomberg.com/profile/company/6265495Z:GR, https://www.continental-automotive.com/en/microsites/test-vehicle-data-protection-questionnaire/realization-platform-and-test-operation.html

Device-type corroboration

FCC equipment authorization filing (ELS 0050-EX-PL-2014, Dec 2013) for an automotive distance-control/ADAS device under this company name, supporting plausible use of this OUI on in-vehicle networked sensor/ECU hardware

Primary-source access note

raw IEEE OUI registry text (standards-oui.ieee.org/oui/oui.txt) returned HTTP 418 on the web pass and was not directly re-fetched; the OUI-to-company mapping instead rests on the cached the IEEE MA-L registry snapshot plus two independent third-party aggregators (udger.com, macvendors.com) [Likely] — https://udger.com/resources/mac-address-vendor-detail?name=adc_automotive_distance_control_system_gmbh, https://api.macvendors.com/3C69D1

Related vendor

Continental AG (parent company) [Confirmed] — https://www.continental-automotive.com/en/microsites/test-vehicle-data-protection-questionnaire/realization-platform-and-test-operation.html

Analyst note

not a bare single-OUI shell — the registrant has independently verifiable corporate substance (commercial register, LEI, D&B/Bloomberg profiles) and product/device context (FCC-filed ADAS distance-control hardware), sufficient to finalize as a real vendor entry despite holding only one known OUI block.
