Bosch Access Systems GmbH — 2 prefixes (MA-L)

A MAC address beginning with 00:10:17 or 00:1B:86 belongs to Bosch Access Systems GmbH, an IEEE-registered vendor holding two MA-L blocks under the identical registrant string and address, Charlottenburger Allee 50, Aachen, Germany. Devices carrying these prefixes are physical access-control hardware — door controllers, card and biometric readers, and keypads — not general-purpose networking gear.

The company traces an unbroken German commercial-register lineage under Aachen registration HRB 1861: originally MICOS-MIKRO-MINI-COMPUTER-SYSTEME Beratungs- und Dienstleistungs-GmbH, later Bosch Access Systems GmbH, and today Radionix GmbH, trading as part of the Keenfinity Group and still marketing "Bosch access control" branded hardware. A Robert Bosch GmbH shareholding was recorded as of September 2025.

The product line built on these prefixes is the Access Modular Controller (AMC2), paired with access-management software (AMS, BIS-ACE, APE). Bosch's own PSIRT published advisory bosch-sa-940448-bt against this exact line: CVE-2021-23842 (an extractable Blowfish key in AMC2 firmware) and CVE-2021-23843 (unauthenticated configuration tools permitting device reconfiguration), fixed in AMS 4.0 / BIS 4.9.1 plus hardened AMC2 firmware.

IEEE's public the IEEE MA-L registry publishes no assignment or registration date for either block. Third-party lookup tools show "initially filed" dates (2007-03-01 for 001B86; 1998-04-22 for 001017), but these are database artifacts of the third-party service, not IEEE facts, and must not be cited as an IEEE registration date.

Analyst note

Two independently-registered MA-L blocks under an identifiable, still-operating access-control vendor (now Radionix GmbH) with a citable product line and vendor security advisory clear the bar for verifiable company substance beyond a bare IEEE registration [Confirmed]
