Panasonic Automotive Systems — 11 prefixes (MA-L/MA-M)

A MAC address beginning with a Panasonic Automotive Systems prefix (for example B0:D8:88 or EC:65:CC) identifies hardware built by Panasonic Automotive Systems, the automotive-electronics arm of Panasonic Holdings — most often an in-vehicle infotainment (IVI) unit, telematics control unit (TCU), or connected-cockpit component rather than a consumer device.

The IEEE registry lists at least eleven separate blocks (nine MA-L, two MA-M) split across four legally distinct Panasonic Automotive entities: Panasonic Automotive Systems Co., Ltd. in Matsumoto and Mie, Japan; Panasonic Automotive Systems Company of America in Peachtree City, Georgia; Panasonic Automotive Systems Asia Pacific (Thailand) Co., Ltd.; and Panasonic Automotive System Malaysia. This multi-country, multi-entity registration pattern is itself evidence of a large, active Tier-1 automotive supplier rather than a small reseller or shell registrant.

Panasonic Automotive Systems ships IVI head units, TCUs, and cockpit displays/sensors for major automakers, and runs a dedicated automotive-cybersecurity program — the VERZEUSE product line, active since 2014, with a 2025 partnership involving Trend Micro and VicOne for in-vehicle intrusion detection. No CVE or MAC-specific vulnerability disclosure tied to these OUI blocks was found in this pass; that absence was not exhaustively confirmed and would need a dedicated CVE/NVD search.

This entry likely should consolidate all four automotive-entity prefix groups rather than map to a single prefix, but that grouping call belongs to the producer/checker. It sits alongside the already-published vendor-panasonic (parent company) and vendor-panasonic-avc-networks entries, which cover separate, non-automotive Panasonic registrant families.

IEEE assignment

9 MA-L blocks (B0:D8:88, 54:5B:86, 74:D7:CA, CC:57:63, 20:E5:9B, EC:65:CC, 0C:65:9A, E0:EE:1B, 24:A8:7D) + 2 MA-M blocks (28:F8:C6:3, F8:75:28:7) → Panasonic Automotive Systems (multiple legal-entity variants) [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry (direct CSV read)

Additional possible block

FA:93:05 (Japan) cited by one web-search angle but not independently confirmed via this pass's direct the IEEE MA-L registry read [Unknown] — flag for checker re-verification

Registry / block classes

MA-L (24-bit) and MA-M (28-bit); no MA-S (36-bit) matches found [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

HQ / registering addresses

5652 Matsumoto City, Nagano, JP; 1578-5 Uegawa-chou, Matsusaka, Mie, JP; 776 Highway 74 South, Peachtree City, GA, US; 101 Moo 2 Teparak Road, Bangsaothong, Samutprakarn, TH; Plot 10, Phase 4, Prai Industrial Estate, Prai, Penang, MY [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

VERZEUSE automotive-cybersecurity platform (vulnerability analysis + intrusion detection for connected vehicles, active since 2014; 2025 Trend Micro/VicOne partnership) [Confirmed] — news.panasonic.com/global/press/en240909-4, en250805-4, vicone.com press release

IEEE assignment date

Unknown / not applicable — IEEE's public OUI/MA-M data publishes no assignment or registration date; no date is fabricated here [Confirmed]

Security vulnerability history

Unknown — no MAC-specific CVE or disclosure was located tied to these OUI blocks in this light pass; a dedicated CVE/NVD search was not performed [Unknown]

Consolidation note

likely should merge all four entity variants (11 prefixes) into one vendor page, distinct from the separately-published vendor-panasonic and vendor-panasonic-avc-networks entries; grouping decision deferred to producer/checker

[Likely] — /mac/vendor/panasonic/, /mac/vendor/panasonic-avc-networks/

Related vendors

Panasonic Corporation (parent, vendor-panasonic, DONE); Panasonic AVC Networks (vendor-panasonic-avc-networks, DONE)

Analyst note

multi-country, multi-entity OUI spread plus a real product line (IVI/TCU hardware) and an active cybersecurity R&D program clear the abstain-on-shells bar — this is not a bare single-OUI registration.
