FRITZ! Technology GmbH — 5 prefixes (MA-L)

FRITZ! Technology GmbH holds five MA-L blocks (0C:C5:74, 48:7F:80, 00:7A:A4, 24:99:00, 1C:23:A2), all registered to the same Berlin address, Alt-Moabit 95, 10559 Berlin. The organization traces to a real, active German GmbH — Handelsregister Berlin-Charlottenburg HRB 23075 B — originally founded in 2004 as AVM Audio-Visuelles Marketing und Computersysteme GmbH, the same entity behind the well-known FRITZ!Box line. In August 2025 the parent AVM group rebranded to FRITZ! GmbH following a 2024 majority-stake acquisition by Imker Capital Partners, and this subsidiary's five prefixes were newly assigned under the post-rebrand FRITZ! Technology GmbH name. A sibling entry already DONE in this pipeline, vendor-avm-audiovisuelles-marketing-und-computersysteme, shares the identical Alt-Moabit 95 address and founding-era name, making it likely — though not register-ID-confirmed — that the two IEEE-registry name snapshots describe the same underlying legal entity at different points in its corporate history. No device-model-level corroboration was found tying these specific five prefixes to a named FRITZ! product, but the corporate lineage strongly implies use on current-generation FRITZ! consumer networking hardware.

IEEE assignment

5 prefixes → FRITZ! Technology GmbH, Berlin, DE [Confirmed] — the IEEE MA-L registry (local IEEE MA-L copy)

Registry / block size

MA-L (24-bit OUI); 5 IEEE prefixes, all sharing one address [Confirmed] — the IEEE MA-L registry

HQ / registered address

Alt-Moabit 95, Berlin, Berlin, DE 10559 (identical across all 5 blocks) [Confirmed] — the IEEE MA-L registry

Registration date

Unknown / not applicable — IEEE's public OUI CSV publishes no date field; not fabricated, not attributed to IEEE. Third-party per-prefix "registered" dates on maclookup.app (007AA4: 2025-11-12; 0CC574: 2025-09-09; 1C23A2: 2026-04-08; 249900: 2026-02-11; 487F80: 2026-06-16) are database indexing artifacts, not IEEE facts.

Legal identity

German GmbH, Handelsregister Berlin-Charlottenburg HRB 23075 B; originally registered 2004-11-02 as "AVM Audio-Visuelles Marketing und Computersysteme GmbH"; active status per aggregator snapshot dated 2025-07-11 [Likely] — https://www.northdata.com/FRITZ!%20Technology%20GmbH,%20Berlin/Amtsgericht%20Charlottenburg%20(Berlin)%20HRB%2023075%20B, https://firmeneintrag.creditreform.de/10559/2010131547/FRITZ_TECHNOLOGY_GMBH

Parent / group structure

FRITZ! Group GmbH (as of ~May 2026); sibling entities FRITZ! GmbH (HRB 57000, the FRITZ!Box manufacturer, formerly AVM GmbH) and FRITZ.com GmbH (HRB 111009), all at the same Berlin address [Likely] — northdata.com HRB 23075 B and HRB 57000 pages

Business purpose

purchase, development, manufacture and sale of data processing and communication technologies, incl. related IP (patents, licenses) [Likely] — northdata.com HRB 23075 B page

Rebrand history

parent AVM (founded 1986, maker of FRITZ!Box) rebranded to FRITZ! GmbH in August 2025 after a 2024 majority-stake acquisition by Imker Capital Partners; this entry's 5 prefixes were assigned under the post-rebrand "FRITZ! Technology GmbH" name (the pre-rebrand "AVM Audio-Visuelles Marketing..." IEEE rows are a separate, already-DONE entry) [Confirmed] — https://www.it-daily.net/en/shortnews-en/fritzbox-manufacturer-avm-becomes-fritz-gmbh, https://www.it-business.de/aus-avm-wird-fritz-a-6923c53404314ba873ac2894232e0434/

Possible same-entity relationship

strong circumstantial match to already-DONE /mac/vendor/avm-audiovisuelles-marketing-und-computersysteme/ — identical Alt-Moabit 95 Berlin address and founding-era name, consistent with the AVM→FRITZ! rebrand story. Working hypothesis, NOT confirmed via a direct register-ID cross-match; operator should evaluate for a naming-variant/consolidation note rather than treat as an unrelated company.

[Likely] — /mac/vendor/avm-audiovisuelles-marketing-und-computersysteme/, the IEEE MA-L registry

Device type corroboration

no forum, vendor knowledge-base, or community MAC-lookup post found tying these 5 specific prefixes to a named FRITZ! device model; inferred likely use on post-Aug-2025 FRITZ! hardware from corporate identity alone, not sourced at device level [Unknown]

Security context

no CVEs/advisories specific to devices carrying these 5 prefixes (expected — blocks only started being assigned Sept 2025); general FRITZ!OS CVE history for the parent group (DNS-rebinding bypass, push-service XSS, firmware-signature issues, cgi-bin/webcm command injection) is already documented on the sibling DONE entry and applies at the group level

Company substance

not a bare single-OUI shell — 5 IEEE blocks, a real active Handelsregister entity, a traceable parent/sibling group structure, founding history to 2004, and a stated business purpose [Confirmed] — the IEEE MA-L registry, northdata.com, creditreform.de
