ALAXALA Networks Corporation — 2 prefixes (MA-L)

ALAXALA Networks Corporation holds two MA-L OUI blocks in the IEEE registry — D4-35-4A and 00-12-E2 — both registered to "ALAXALA Networks Corporation" at addresses in Kashimada, Saiwai-ku, Kawasaki-shi, Kanagawa, Japan. ALAXALA is a Japanese fabless networking-hardware vendor whose "AX" product family spans enterprise and service-provider Ethernet switches (Layer 2 and Layer 3, both box-type and chassis-type) and high-end routers, sold primarily inside Japan. The company began operations on October 1, 2004 as a joint venture between the networking-hardware divisions of Hitachi and NEC; Fortinet, Inc. acquired a 75% controlling stake on August 31, 2021. Hardware is manufactured at Hitachi's factory in Hadano, Kanagawa. Because OUI consolidation by vendor is more useful than per-prefix pages, both blocks resolve to this single ALAXALA entry. The critical data-quality caveat for any ALAXALA OUI work mirrors every IEEE block: the IEEE Registration Authority publishes no assignment date, so any "date registered" shown on third-party MAC lookup tools is a database artifact rather than an IEEE fact, and is not reproduced here. A globally-administered ALAXALA OUI reliably identifies genuine ALAXALA AX-series hardware for asset classification; its absence does not imply "not ALAXALA," since locally-administered or randomized addresses do not resolve to any vendor.

IEEE assignment (prefix 1)

D4-35-4A → ALAXALA Networks Corporation, registry address Shinkawasaki Mitsui Bldg. West Tower 13F, 1-1-2 Kashimada, Saiwai-ku, Kawasaki-shi, Kanagawa-ken, JP 212-0058 [Confirmed] — IEEE MA-L (oui.csv line 743)

IEEE assignment (prefix 2)

00-12-E2 → ALAXALA Networks Corporation, registry address 890 Kashimada, Saiwai-ku, Kawasaki-shi, Kanagawa-ken, JP 212-0058 [Confirmed] — IEEE MA-L (oui.csv line 36755)

Registry / block size

MA-L (24-bit OUI); 2 IEEE prefixes on record [Confirmed] — enrichment/registries/oui.csv (no matches in mam.csv or oui36.csv). NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Brand-name origin

Security context

CVEs on record (CVEDetails vendor_id 3072 / OpenCVE). Most-documented is CVE-2005-0356 (CERT VU#637934) — a TCP timestamp-validation flaw in the AX series allowing a remote attacker with knowledge of connection endpoints to inject TCP segments and drop legitimate traffic (DoS), disclosed May 2005; a BGP UPDATE-driven route-flapping DoS is also documented. Real-world incident: an August 24, 2012 Tokyo Stock Exchange core-system outage was attributed to software bugs in ALAXALA hardware, halting trading in 241 securities. AX2600S series is positioned with built-in Zero Trust / micro-segmentation; post-Fortinet, integration with FortiGate and the Fortinet Security Fabric is a stated direction.

Analyst note

An ALAXALA OUI on a globally-administered address identifies genuine ALAXALA AX-series hardware; absence does not mean "not ALAXALA" (locally-administered/randomized addresses do not resolve to any vendor). ALAXALA hardware is overwhelmingly deployed inside Japan, so these OUIs are a strong locality signal in enterprise/carrier inventories.
