4IPNET, INC. — OUI 00:1F:D4 (MA-L)

4ipnet, Inc. holds a single IEEE MA-L block, 00:1F:D4, registered to "4IPNET, INC." at 38129 Cambridge Court, Fremont, CA, US 94536 — a US registration address for a company whose engineering and market presence was Taiwan-based (Taipei, founded 2002). This is not a bare shell registration: 4ipnet was a genuine enterprise and carrier Wi-Fi vendor whose gear appears in named product lines, distributor catalogues, and partner case studies. Its portfolio centered on wireless LAN gateway-controllers (the WHG series, e.g. WHG315 and WHG801), indoor and outdoor access points, and wireless hotspot gateways with captive-portal and network-access-control features, sold into hospitality, education, carrier public-Wi-Fi, and enterprise markets. Documented deployments include Taiwan public-Wi-Fi hotspots (via Chunghwa Telecom) and hotel installations such as Adrián Hoteles in Tenerife. The company now appears defunct: third-party company trackers list it as inactive/deadpooled and its official domain (4ipnet.com) failed to resolve during research, so product details were corroborated through search snippets, reseller pages, and a partner press release rather than a live vendor site. No CVEs specifically naming 4ipnet or its WHG products were found; a search collision with the unrelated Wind River/Interpeak "IPnet" TCP/IP stack (Urgent/11) is a name match only and does not apply to this vendor.

IEEE assignment

OUI 00-1F-D4 → 4IPNET, INC. [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); single block, no MA-M or MA-S entries found (searched the IEEE MA-M registry / the IEEE MA-S registry, no matches) [Confirmed] — IEEE MA-L (the IEEE MA-M registry, the IEEE MA-S registry)

Registry address / country

38129 Cambridge Court, Fremont, CA, US 94536 (US registry address) [Confirmed] — IEEE MA-L

Company origin

Taiwan-based (Taipei), founded 2002 [Likely] — Tracxn / Crunchbase company profiles (single-source founding/location; corroborated by Taiwan carrier partnership)

Company status

appears defunct / inactive; official domain 4ipnet.com did not resolve during research [Likely] — Tracxn (lists as deadpooled); DNS non-resolution of www.4ipnet.com observed during research

Device types

wireless LAN gateway-controllers (WHG series, e.g. WHG315, WHG801), indoor/outdoor access points, wireless hotspot gateways with captive-portal / NAC [Confirmed] — 4ipnet product pages (via search snippets), reseller/distributor catalogues

Usage context

enterprise, carrier, and hospitality/education Wi-Fi infrastructure — not consumer/home gear [Confirmed] — 4ipnet product pages; PRNewswire hotel-deployment release

Notable deployments

Taiwan public-Wi-Fi hotspots (Chunghwa Telecom); Adrián Hoteles (Tenerife) [Likely] — PRNewswire release (hotel); partner references (Chunghwa, single-source)

Security context

no CVEs or advisories specifically naming 4ipnet / WHG products; the "IPnet" Urgent/11 stack (Wind River/Interpeak, CVE-2019-12255 et al.) is a name collision, NOT this vendor [Confirmed] — CVE/advisory search returned no 4ipnet-specific hits; CISA ICSA-19-274-01 documents the unrelated IPnet stack

Registration date

none published — IEEE does not publish OUI assignment dates; the "registered 2008-02-02" figure on maclookup.app is a third-party database artifact, not an IEEE fact, and is not recorded as an authoritative allocation date

[Confirmed] — IEEE the IEEE MA-L registry has no date column; maclookup.app date is third-party

Verified prefix

00:1F:D4 (MA-L, 4IPNET, INC.) [Confirmed] — IEEE MA-L

Analyst note

single-OUI vendor; a 00:1F:D4 address reliably identifies 4ipnet-origin hardware, but the vendor being defunct means no further firmware/security updates — an operational-risk signal for any 4ipnet gear still in service.
