AUMOVIO Germany GmbH — 3 prefixes (MA-L)

AUMOVIO Germany GmbH holds three IEEE MA-L blocks — 44:20:63, E4:1E:33, and 40:82:56 — each registered to a different German plant address (Regensburg, Villingen-Schwenningen, and Babenhausen respectively). The company is the former Continental Automotive GmbH: Continental AG spun off its automotive division as Aumovio SE, which began trading on the Frankfurt Stock Exchange on 2025-09-18, and the German operating subsidiary carries these OUI registrations. The hardware behind these prefixes is automotive Tier-1 embedded gear — electronic control units (ECUs), telematics modules for fleet, heavy-duty, and two-wheeler connectivity, zone control units, in-vehicle CAN/Ethernet networking boards, and cockpit/infotainment compute units. These are B2B components destined for vehicle-OEM integration, not consumer or enterprise IT networking equipment, so an AUMOVIO OUI on a network most plausibly indicates an embedded automotive interface rather than a desktop or appliance. A naming caveat for any matching work: a distinct legal entity, "AUMOVIO Autonomous Mobility Germany GmbH" (Ingolstadt, prefix F0:30:12), shares the country but not the legal name, and "AUMOVIO Systems, Inc." (a separate, likely US, entity) holds its own additional blocks — keep these registrations separate. As with all OUI data, IEEE publishes no assignment dates, so any "date registered" shown by third-party lookup tools is a database artifact, not an IEEE fact.

Aumovio runs a public PSIRT (psirt@aumovio.com) and Product Vulnerability Disclosure Program, is an Auto-ISAC member, and follows the FIRST PSIRT Framework; no CVEs specifically attributed to AUMOVIO Germany GmbH devices found in this pass [Confirmed for program; no-CVE is absence-of-evidence] — https://www.aumovio.com/en/company/corporate-governance/product-vulnerability-disclosure-program.html

Analyst note

an AUMOVIO Germany OUI identifies an automotive Tier-1 embedded interface (ECU / telematics / in-vehicle networking), not consumer or enterprise IT gear — useful for classifying a device as automotive, but these blocks are not expected on general office networks.
