ACKSYS Communications & Systems — 00:09:90 (MA-L)

ACKSYS Communications & Systems holds a single confirmed IEEE MA-L block, 00:09:90, registered to "ACKSYS Communications & systems" at ZA du Val Joyeux, Villepreux, France (F-78450). Holding only one OUI does not make this a bare shell registration: ACKSYS is a French industrial-networking manufacturer founded in 1984, with a real, named product catalog — AirBox, RailBox, AirLink, AirXroad, RailTrack, AirWan, the RuggedAir100/1000 line, and WaveManager management software — sold into rail and mass-transit, industrial IIoT, mining, and oil-and-gas markets, all device classes that plausibly embed vendor-owned MAC hardware (industrial WiFi access points, cellular routers, Ethernet bridges). A separate MA-M (28-bit) block, 58:AD:08:60/28, is registered under the shorter name "ACKSYS" at a different Villepreux street address; the org-string and address differ enough from the MA-L registrant that it is flagged here as a related-name candidate rather than merged into this entry. No IEEE assignment date exists for either block — a third-party aggregator (maclookup.app) lists 05 June 2002 as a "registered" date, but that is a database artifact, not an IEEE-published fact, and is recorded only with that caveat. Direct IEEE registry fetch was blocked (HTTP 418) in this pass, so the org/OUI mapping rests on the cached registry CSV plus third-party corroboration rather than a fresh live IEEE fetch.

Registry / block

MA-L (24-bit OUI), prefix 00:09:90 [Confirmed] — the IEEE MA-L registry

Organization name (exact, IEEE)

ACKSYS Communications & systems [Confirmed] — the IEEE MA-L registry

Registered address

ZA du Val Joyeux, Villepreux, FR F-78450 [Confirmed] — the IEEE MA-L registry

Company substance

identifiable, substantive French industrial-networking manufacturer, est. 1984, with a real product catalog (AirBox, RailBox, AirLink, AirXroad, RailTrack, AirWan, RuggedAir100/1000, WaveManager) targeting rail/transit, industrial IIoT, mining, and oil & gas — not a bare single-OUI shell [Confirmed, corroborated by two independent web sources] — https://www.acksys.fr/en/company/who-we-are/, https://www.directindustry.com/prod/acksys-communications-systems-8580.html, https://masstransit.network/mass-transit-industry/acksys-communications-systems

Device-type corroboration

product line (industrial WiFi access points, cellular routers, Ethernet bridges for rail/industrial markets) is consistent with a manufacturer that embeds its own MAC OUI in networked hardware [Likely] — https://www.acksys.fr/en/

Related MA-M block (not merged)

58:AD:08:60/28 registered to the shorter name "ACKSYS" at a different Villepreux address (10 rue des entrepreneurs vs ZA du Val Joyeux); same city/country, distinct org-string and address, so treated as a related-name candidate only [Confirmed as a distinct registry row; identity with this entry Unknown] — the IEEE MA-M registry

OUI36 / MA-S match

none found for ACKSYS [Confirmed absence] — the IEEE MA-S registry (no matching row)

Registration date

Unknown — IEEE publishes no assignment/registration date for OUI/MA-M/MA-S rows; a third-party aggregator (maclookup.app) lists "05 June 2002" as registered / "17 November 2015" as last updated, but this is a database artifact, not an IEEE fact, and is not attributed to IEEE [Confirmed as Unknown per no-fabrication rule] — https://maclookup.app/vendors/acksys-communications-systems

IANA Reference

not applicable / left blank — no IANA Reference data exists for OUI registry rows [Confirmed]

Security / CVE context

ACKSYS hosts an "802.11 specification vulnerabilities: CVE Alerts" page, but it is gated behind a site-member login; no specific CVE numbers or advisories were retrievable, and no independent NVD/CVE entries were found [Unknown] — https://www.acksys.fr/en/cve-alerts/
