AUMOVIO Systems, Inc. — 6 prefixes (MA-L)

AUMOVIO Systems, Inc. holds six MA-L blocks in the IEEE registry — 00:1E:AE, 00:54:AF, 20:AD:56, 34:22:CF, 8C:5F:48, and D4:94:FB — registered to a US automotive-electronics entity (Morganton, North Carolina; the registry also lists 21440 W. Lake Cook Rd., Deer Park, IL and one block at 3901 North First Street, San Jose, CA). AUMOVIO Systems is the US arm of AUMOVIO SE, a German automotive-technology group spun off from Continental AG's Automotive sector in September 2025 and listed on the Frankfurt Stock Exchange (ticker AMV0) on 2025-09-18. The hardware behind these OUIs is embedded automotive equipment, not enterprise or consumer networking gear: in-vehicle Network ECUs (gateway control units routing CAN/LIN/Automotive Ethernet traffic, up to 10-port 100/1000BASE-T1, with hardware security modules and AUTOSAR support) and Telematics Control Units (4G/5G/Wi-Fi/Bluetooth 5.2/V2X/eCall/OTA modules for cars, trucks, buses, and off-highway vehicles). The practical consequence for MAC classification: one of these prefixes appearing in traffic most likely indicates an in-vehicle telematics or gateway ECU — a connected car phoning home, an OTA update, or fleet telematics — rather than IT infrastructure. A registrant caveat worth noting: a legally distinct sister entity, AUMOVIO Systems Romania S.R.L. (prefix D4:00:CA, Sibiu, RO), also appears in the registry and should not be conflated with the US "AUMOVIO Systems, Inc." that owns the six blocks above. As with all OUI work, no IEEE-issued registration date exists for these blocks — third-party "date registered" values are database artifacts, not IEEE facts.

IEEE assignment

6 prefixes → AUMOVIO Systems, Inc. [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L (24-bit OUI); 6 IEEE prefixes [Confirmed] — the IEEE MA-L registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); the "date registered" values on third-party tools (maclookup.app shows a range from 2007 to 2026 for this vendor) are database artifacts, not IEEE facts.

Security context

no AUMOVIO-specific CVEs found in public search [Likely — single-search abstention, not refutation] — public CVE search. General note: automotive telematics ECUs (TCUs/Network ECUs) with cellular/Wi-Fi/Bluetooth/V2X radios are a known attack-surface category; AUMOVIO TCUs advertise HSMs and intrusion detection, and Network ECUs include firewall capabilities [Confirmed of product features] — https://engineering-solutions.aumovio.com/components/tcu/, https://engineering-solutions.aumovio.com/components/network-ecus/

Analyst note

a prefix from this vendor in network traffic most likely indicates an in-vehicle telematics or gateway ECU (connected car, OTA update, fleet telematics), not enterprise IT, consumer routers, or general-purpose networking.
