Robert Bosch SRL — 1 prefix (MA-L)

"Robert Bosch SRL" is the distinct Romanian legal entity through which Bosch Group operates its Bucharest engineering and manufacturing footprint, and it holds exactly one IEEE MAC-prefix assignment: the 24-bit MA-L block 84:3C:4C, registered at Horia Macelariu 30-34, Bucharest 013937, Romania. It sits inside a much larger Bosch corporate family in these registries — at least 20 other MA-L rows plus MA-M/MA-S blocks are registered to sibling Bosch entities (GmbH main, JuP1 Mexico, Elektronika/Elektronikai Kft Hungary, Smart Home GmbH, Healthcare GmbH, LLC Automotive Electronics, Engineering and Business Solutions India), each tracked as its own vendor entry in this repository — but 84:3C:4C is the sole block registered under the exact "Robert Bosch SRL" org string. Independent corroboration (the parent's own Romania site, a EMIS company-financial profile, and Romanian trade press covering a facility expansion) documents Robert Bosch SRL as a substantive operating business combining an R&D engineering center with Industry 4.0 smart-factory production, part of a roughly 9,900-employee Bosch Romania operation spanning Bucharest, Cluj-Napoca, and Sibiu — not a bare shell registration.

Company substance

Robert Bosch SRL is the operating Romanian arm of Bosch Group (global HQ Robert Bosch GmbH, Stuttgart), combining an R&D engineering hub with Industry 4.0 smart-factory production in Bucharest, part of a ~9,900-employee Bosch Romania operation across Bucharest, Cluj-Napoca, and Sibiu, with an independently reported EUR 25M engineering-center expansion [Confirmed] — https://www.bosch.ro/en/our-company/bosch-in-romania/bosch-engineering-center/, https://www.emis.com/php/company-profile/RO/Robert_Bosch_SRL_en_1492830.html, https://www.romania-insider.com/bosch-expands-buchares-center-apr-2022, https://www.energynomics.ro/en/bosch-engineering-center-expands-its-development-activities-in-bucharest/

Registration date

Unknown / not applicable — IEEE's public the IEEE MA-L registry publishes no assignment/registration date column; the third-party lookup checked (hwaddress.com) also surfaces no date field for this row, so no date — real or artifact — is recorded

[Confirmed absence] — the IEEE MA-L registry, https://hwaddress.com/company/robert-bosch-srl/

Device-type / product mapping

Unknown — no vendor datasheet, teardown, or device database ties 84:3C:4C to a named product line; consistent with an OUI used for internal enterprise or manufacturing-floor networking rather than a retail SKU [Unknown]

Security context

vendor-level, Bosch operates a formal PSIRT publishing product security advisories (e.g. a 2018 IP-camera CVE-2018-19036 advisory) and CVE trackers list numerous Bosch-branded product vulnerabilities generally, but no source ties any specific CVE or incident to this OUI or to Robert Bosch SRL specifically [Likely] — https://psirt.bosch.com/security-advisories/, https://media.boschsecurity.com/fs/media/pb/security_advisories/bosch-2018-1202-bt-cve-2018-19036_security_advisory_ip_camera_vulnerability.pdf, https://www.cvedetails.com/vulnerability-list/vendor_id-19870/Bosch.html
