Aptiv Services US, LLC — 4 prefixes (MA-L)

A MAC address beginning with 00:22:A0, 28:63:BD, 44:1D:B1, or 64:69:11 belongs to Aptiv Services US, LLC, the US-registered entity of Aptiv PLC, a large Tier-1 automotive electronics and software supplier. These blocks most plausibly identify automotive Ethernet-networked hardware — ADAS controllers, cockpit compute modules, or vehicle gateway units — rather than standalone consumer or IT devices.

Aptiv PLC (NYSE: APTV, S&P 500) is the renamed successor to Delphi Automotive Systems, adopting the Aptiv name in December 2017 after spinning off Delphi Technologies. The company reports roughly 140,000 employees, $20.4B in 2025 revenue, and operations across 139 manufacturing facilities and 11 technical centers in 50 countries. Its product segments include ADAS, Digital Cockpit, Advanced Compute, and Connection Systems, and it acquired Wind River Systems in January 2022.

Four independent MA-L assignments to the same registrant name and Troy, MI address is the classic multi-OUI pattern of a sustained production vendor, which is why this entry treats Aptiv as a substantive company rather than a bare single-OUI shell. What could not be confirmed this pass: which specific product line or facility any of the four prefixes attach to, and whether any Aptiv-branded network device has a public CVE history — a general web search tool was unavailable, so verification relied on targeted page fetches rather than open search.

IEEE's public OUI registry (the IEEE MA-L registry) publishes no assignment or registration date for any prefix. Third-party "date registered" values seen on lookup sites are database artifacts of those tools, not IEEE facts, and are not reproduced here as registration dates.

Registration dates

IEEE the IEEE MA-L registry publishes no date column / no assignment date for any prefix. Third-party dates seen on maclookup.app (2008-10-25, 2019-11-14, 2023-06-15, 2025-09-15) are database artifacts of that tool, not IEEE facts [Confirmed absence of IEEE date; the third-party dates themselves Unknown/unverified] — maclookup.app/vendors/aptiv-services-us-llc

Specific facility mapping

could not confirm that 5725 Innovation Drive, Troy, MI maps to a specifically named Aptiv facility via public web sources this pass (aptiv.com locations pages 404'd) [Unknown]

Security history

no CVEs or public vulnerability disclosures found naming Aptiv-branded network devices/ECUs this pass (NVD not directly queryable); one unrelated historical hardware-safety incident (Delphi ignition switches, 2014 GM Cobalt recall) predates the 2017 Aptiv rebrand and is not a network vulnerability [Unknown re: CVEs; Likely re: the 2014 recall being unrelated] — en.wikipedia.org/wiki/Aptiv

Analyst note

four independent MA-L assignments to one entity/address over a multi-year span is the standard multi-OUI production pattern; treat this as a genuine automotive Tier-1 vendor for classification purposes, but don't assume any single prefix maps to a specific vehicle system without further confirmation.
