ACCESS CO., LTD. — 00:80:32 (MA-L)

The OUI prefix 00:80:32 is registered with the IEEE to ACCESS CO., LTD., a Tokyo-based Japanese software company at the registry address "HIEI-KUDAN BLDG. B1, JP" (no street, city, or postal code populated in the IEEE record). The assignment is a single MA-L block (a full 24-bit OUI, ~16.7 million addresses) — no companion MA-M or MA-S block was found under the same organization name. Unlike many single-OUI registrants, ACCESS CO., LTD. is a substantive, currently operating company: founded in 1979 and incorporated in 1984, it is publicly traded on the Tokyo Stock Exchange (ticker 4813), employs roughly 795 people, and reported FY revenue of approximately JPY 19.22 billion (up 20.62% year-over-year) as of the most recent figures checked. Its flagship product line is the NetFront family of embedded browsers, historically deployed in over one billion devices spanning feature phones, i-mode handsets, set-top boxes, Nintendo Switch, PlayStation consoles, and automotive infotainment systems; it also sells network-operating-system products (OcNOS, VirNOS, ZebOS) and a digital-publishing platform (PUBLUS). NTT publicly announced a share acquisition in ACCESS CO., LTD. in December 2023, corroborating the company's continued market relevance. That said, no product datasheet or teardown was located that explicitly ties hardware to the 00:80:32 prefix itself — the company's business is software-centric, so the concrete device population behind this specific OUI stays unconfirmed even though the company's identity and substance are well established.

IEEE assignment

00:80:32 → ACCESS CO., LTD. [Confirmed] — IEEE the IEEE MA-L registry (line 38150)

Registry / block size

MA-L (24-bit OUI; ~16.7M addresses) [Confirmed] — IEEE the IEEE MA-L registry

Registered address / country

HIEI-KUDAN BLDG. B1, JP (Japan); no street/city/postal fields populated — a thin but genuine IEEE record, verified against raw registry bytes [Confirmed] — IEEE the IEEE MA-L registry

Allocated date

Unknown — IEEE publishes NO registration/assignment date for OUI entries (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address). maclookup.app shows "initially registered on 09 November 2000," which is a third-party database artifact, not an IEEE fact, and must not be surfaced as one.

Hardware / device linkage to 00

80:32: no product datasheet or teardown was located that explicitly ties hardware to this specific OUI; the company's business is software-centric (browsers, OS layers, IoT agents) rather than device manufacturing

[Unknown] — absence of finding across https://www.access-company.com/en/ and general search

Security context

NetFront Life Browser for Android (v2.2.0/2.3.0) carries CVE-2012-1485 (unspecified vulnerability); NetFront Browser NX (WebKit-based, used in Nintendo Switch) was implicated in a jailbreak chain that reused a previously-disclosed WebKit exploit, CVE-2016-4657 — a WebKit-inherited issue, not an ACCESS-authored flaw. No CVEs or threat-actor activity are tied to the 00:80:32 hardware OUI itself.

Analyst note

A 00:80:32 globally-administered address identifies genuine ACCESS CO., LTD.-issued hardware, but the company's core business is software (embedded browsers, network OS), not hardware manufacturing, and only one OUI block is registered to it — expect a small, mixed device population rather than a dominant hardware footprint.
