AIM GmbH — Avionics Databus Interface & Test Systems (MA-L 08:79:99)

AIM GmbH holds a single IEEE MA-L block, 08:79:99, registered under the organization name "AIM GmbH" at an address in Freiburg im Breisgau, Germany — though the registry's own country field oddly says "US," an apparent data-entry artifact rather than a fact about the company. The registrant traces to AIM Gesellschaft für angewandte Informatik und Mikroelektronik mbH, an operating company founded in 1989 and still active, registered at Amtsgericht Freiburg (HRB 3520). AIM designs and manufactures avionics databus test, simulation, and analysis hardware and software: interface modules and embedded test systems supporting MIL-STD-1553, STANAG 3910/EFEx, ARINC 429, AFDX/ARINC 664 P7, Fibre Channel, ARINC 825, and Ethernet up to 10 Gbit/s, alongside the PBA.pro test/analysis/simulation software suite. Several of these product lines are literally Ethernet/AFDX-based avionics networking gear, which is direct corroboration for why the company needed a MAC OUI block in the first place — this is a real, identifiable, 37-year-old company with concrete device context, not a bare registration. A collision worth flagging for pipeline hygiene: a separate, unrelated MA-M block (D0:22:12) is registered to a different entity also named "AIM," located in Meylan, Isère, France, with no evident corporate link to AIM GmbH — it is not a second assignment for this vendor. No CVEs or public security advisories were found for AIM's product line in this research pass; the devices are specialist aerospace/defense test-bench equipment rather than consumer or enterprise network gear, so general MAC-based fingerprinting exposure for this vendor is low but not independently documented.

IEEE assignment

MA-L 08:79:99 → "AIM GmbH," registry address Sasbacherstraße 2, Freiburg, BW, listed country "US" [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L (24-bit OUI); single assignment — no second OUI/MA-M/MA-S block found for this entity across the IEEE MA-L registry, the IEEE MA-S registry, or the IEEE MA-M registry [Confirmed] — the IEEE MA-L registry, the IEEE MA-S registry, the IEEE MA-M registry (full scan, this cycle)

HQ / country

Sasbacherstraße 2, Freiburg im Breisgau, Baden-Württemberg, Germany; the registry's own "US" country token is a data-entry anomaly — street, city, and state abbreviation are unambiguously German [Confirmed identity; Likely re: anomaly explanation] — the IEEE MA-L registry; https://www.aim-online.com

Company status

active — full legal name AIM Gesellschaft für angewandte Informatik und Mikroelektronik mbH, Amtsgericht Freiburg HRB 3520, founded 1989 [Confirmed] — https://www.northdata.com/AIM%20Gesellschaft%20f%C3%BCr%20angewandte%20Informatik%20und%20Mikroelektronik%20mbH,%20Freiburg%20i%C2%B7%20Breisgau/Amtsgericht%20Freiburg%20HRB%203520, https://www.companyhouse.de/en/AIM-Gesellschaft-fuer-angewandte-Informatik-und-Mikroelektronik-mbH-Freiburg-im-Breisgau

Device types

avionics databus test, simulation, and analysis hardware/software — interface modules and embedded test systems for MIL-STD-1553, STANAG 3910/EFEx, ARINC 429, AFDX/ARINC 664 P7, Fibre Channel, ARINC 825, and Ethernet (up to 10 Gbit/s) [Confirmed] — https://www.aim-online.com

Notable products

PBA.pro test/analysis/simulation software suite [Confirmed] — https://www.aim-online.com

Registered date

Unknown/none — IEEE's public OUI registry publishes no assignment/registration date for any MA-L/MA-M/MA-S row; not to be confused with RIR/ASN allocation dates, which are a separate first-party fact. A third-party MAC-lookup source was checked and also shows no date for this prefix, so none is recorded.

[Confirmed] — the IEEE MA-L registry; https://www.cleancss.com/mac-lookup/08-79-99

Related-entity collision (not counted)

MA-M block D0:22:12, org name exactly "AIM," registered in Meylan, Isère, France — no evident corporate link to AIM GmbH; excluded as a second assignment for this vendor [Confirmed] — the IEEE MA-M registry

Security context

no CVEs or public vulnerability disclosures found for AIM's avionics interface hardware in this research pass; devices are specialist aerospace/defense test-bench equipment, not consumer/enterprise network gear [Unknown — absence of finding, not a confirmed clean bill] — (no source; negative search result)

Analyst note

single-OUI registrant, but backed by a real, decades-old, still-active company with concrete product/device context (Ethernet/AFDX-based avionics networking hardware) — sufficient verifiable substance beyond the bare IEEE registration.
