AVM Audiovisuelles Marketing und Computersysteme GmbH — 20+ prefixes (MA-L)

AVM Audiovisuelles Marketing und Computersysteme GmbH is the legal name under which a large block of MA-L OUIs are registered to the Berlin-based consumer-networking manufacturer best known for its FRITZ!Box line. Founded in 1986, the company ships DSL, cable, fibre, and LTE broadband routers along with Wi-Fi mesh repeaters, powerline adapters, VoIP and DECT cordless phones, and FRITZ!DECT smart-home devices (thermostats, plugs, LED lights). The FRITZ!Box — a combined modem, router, Wi-Fi access point, and PBX, first shown at CeBIT in 2004 — is the flagship and the brand carries a dominant share of the German home-router market, with current Wi-Fi 7 models such as the 7690. In July–August 2025 the company rebranded to FRITZ! GmbH and avm.de now redirects to fritz.com, but the historical legal name is retained on the IEEE registration, so devices seen with these prefixes are almost certainly AVM/FRITZ! consumer or SMB networking gear, predominantly on European (chiefly German) home networks. The registrant is a well-known, legitimate manufacturer — not an obscure or suspicious vendor. As with all OUI work, IEEE publishes no registration dates for these blocks; any "date registered" on third-party MAC-lookup tools is a database indexing artifact, not an IEEE fact.

Security context

multiple historical CVEs in FRITZ!Box / FRITZ!OS (e.g. DNS-rebinding bypass < 7.21, push-service XSS < 6.30, improper firmware-signature verification < 6.30 enabling code execution, remote command injection via cgi-bin/webcm, PPPoE padding info leak on 7490). AVM ships FRITZ!OS updates and maintains a public security-advisories page; guidance is to run the latest FRITZ!OS

Analyst note

risk is moderate-to-elevated only for unpatched/older firmware; FRITZ!Box is widely deployed in German homes and is a meaningful attack surface, but devices on current FRITZ!OS with auto-update are generally well-maintained consumer gear
