Fujitsu Technology Solutions GmbH — 3 prefixes (MA-L)

Fujitsu Technology Solutions GmbH (FTS) holds three IEEE MA-L blocks — 00:19:99, 90:1B:0E, and 4C:52:62 — registered to the company's Augsburg address (Buergermeister-Ulrich-Strasse 100, 86199 Augsburg, Bayern, Germany). FTS was the EMEIA-facing subsidiary of Fujitsu Limited (Japan), formed in 2009 when Fujitsu bought out Siemens' half of the earlier Fujitsu Siemens Computers joint venture (1999). The MAC prefixes appear across an enterprise hardware portfolio: PRIMERGY and PRIMEQUEST x86 servers, CELSIUS workstations, ESPRIMO desktops, LIFEBOOK notebooks, FUTRO thin clients, and ETERNUS storage. A practical detail for network operators: PRIMERGY servers ship with an iRMC (integrated Remote Management Controller), a BMC-class out-of-band management interface that carries its own MAC and can run on a dedicated service LAN — so a Fujitsu OUI on a network may belong either to a system NIC or to a management controller, and an exposed iRMC is a high-value out-of-band target. Seeing one of these prefixes strongly implies an enterprise IT asset (corporate or data-center), not a consumer device. The IEEE registry publishes no allocation date for any of these prefixes; third-party "date registered" values seen on MAC-lookup sites are database artifacts, not IEEE facts.

IEEE assignment

3 prefixes → Fujitsu Technology Solutions GmbH, registered Augsburg, Bayern, DE [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); holds 3 IEEE prefixes (~16.7M addresses each, ~50.3M combined) [Confirmed] — IEEE MA-L; maclookup.app, hwaddress.com. NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools (e.g. 00:19:99=2006, 90:1B:0E=2012, 4C:52:62=2017) is a database artifact, not an IEEE fact.

HQ / country

Buergermeister-Ulrich-Strasse 100, 86199 Augsburg, Bayern, DE (registry address; corporate/EMEIA HQ historically Munich) [Confirmed] — IEEE MA-L, hwaddress.com. NOTE: the 00:19:99 registry row omits the 'Bayern' state field.

Company status

FTS was the EMEIA arm of Fujitsu Limited; Fujitsu has since consolidated global operations and fts.fujitsu.com redirects to fujitsu.com/fts. Augsburg manufacturing/support continues. No specific dissolution date confirmed. [Likely] — fujitsu.com/fts

Device types

PRIMERGY / PRIMEQUEST servers, CELSIUS workstations, ESPRIMO desktops, LIFEBOOK notebooks, STYLISTIC tablets, FUTRO thin clients, ETERNUS storage [Confirmed] — en.wikipedia.org/wiki/Fujitsu_Technology_Solutions, fujitsu.com

Notable products

enterprise x86 servers (PRIMERGY/PRIMEQUEST) and the iRMC management controller

Company background

FTS established 2009 as a wholly-owned subsidiary of Fujitsu Limited (Japan), after Fujitsu bought out Siemens' 50% of the Fujitsu Siemens Computers JV (founded 1999); served EMEIA markets; ~5,087 staff as of 2011. [Confirmed] — en.wikipedia.org/wiki/Fujitsu_Technology_Solutions

Management interface (iRMC)

PRIMERGY servers include an iRMC (integrated Remote Management Controller), a BMC/out-of-band interface with its own LAN port and MAC, configurable as shared LAN or dedicated service LAN; these OUIs plausibly appear on both system NICs and iRMC ports. [Likely] — blog.paessler.com, docs.redhat.com

Security context

Fujitsu PSIRT actively publishes advisories. Notable: NIC/driver DoS (CVE-2021-32537) across CELSIUS/LIFEBOOK/STYLISTIC/PRIMERGY/PRIMEQUEST/ETERNUS; Intel CSME/AMT/ISM privilege-escalation and DoS issues; Fujitsu Infrastructure Manager (ISM) pre-2.8.0.061 cleartext credential storage (CISA ICSA-23-255-02). An exposed iRMC is a high-value out-of-band target.

Analyst note

A Fujitsu Technology Solutions OUI on a network strongly indicates an enterprise IT asset (server, workstation, thin client, or its management controller) in an EMEIA corporate/data-center context, not a consumer device. Distinguish a system-NIC MAC from an iRMC management-interface MAC when triaging.
