Allied Telesis — 13 prefixes (MA-L)

Allied Telesis holds 13 MA-L (24-bit OUI) blocks in the IEEE registry, spread across several subsidiary entities rather than a single corporate name — a pattern typical of a global networking vendor that grew through regional incorporation. The registered organizations include Allied Telesis, Inc. (US), Allied Telesis K.K. (Japan), Allied Telesis Labs Ltd (New Zealand), Allied Telesis Labs, Inc. (US), Allied Telesis International Corporation (US), and Allied Telesis (Hong Kong) Ltd., with registry addresses in Sunnyvale and San Jose CA, Raleigh NC, Tokyo, Christchurch, Milan, and Hong Kong. The company traces to 1987 (incorporated as System Plus Co. in March 1987 and renamed Allied Telesis K.K. that September) and is a networking-equipment manufacturer whose hardware spans enterprise and industrial Ethernet switches (Layer 2/3), VPN routers, UTM firewalls, wireless access points, media converters, and transceivers — including ruggedized industrial IE-series switches aimed at OT/ICS environments. Because the OUIs sit under multiple legal names, consolidating them into one vendor entry is more useful than minting near-identical per-prefix pages. As with every IEEE OUI record, no registration date is published: the "date registered" values shown on third-party MAC-lookup sites (e.g. 1998-04-22 for 00:00:F4) are database artifacts of those services, not IEEE-sourced facts, and must not be presented as IEEE registration dates.

13 MA-L prefixes across Allied Telesis subsidiary names [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv; https://regauth.standards.ieee.org/standards-ra-web/pub/view.html#registries)

Registry / block size

MA-L only (24-bit OUI); 0 MA-M and 0 MA-S entries. 13 prefixes ≈ 218M addresses [Confirmed] — IEEE registry (local cached MA-L/MA-M/MA-S CSVs). NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Analyst note

prefixes are registered under several legal names, so a MAC-vendor lookup may surface "Allied Telesis K.K." or "Allied Telesis Labs" rather than "Allied Telesis, Inc." — all map to the same vendor group.
