CNET Technology, Inc. — 2 prefixes (MA-L)

A MAC address beginning with 00:08:A1 or 00:80:AD belongs to CNET Technology, a Taiwan-founded networking-hardware maker with a California office, and typically shows up on Ethernet NICs, switches, wireless/broadband routers, Wi-Fi adapters, ADSL modems, or media converters rather than on end-user consumer devices.

The two OUIs register separately and to different addresses: 00:08:A1 to "CNet Technology Inc." at Hsinchu Science Park, Taiwan, and 00:80:AD to "CNET TECHNOLOGY, INC." at 2199 Zanker Road, San Jose, CA. No related MA-M or MA-S sub-block was found under either name, so the company's IEEE footprint is just these two dedicated MA-L blocks.

Independent sources (Wikipedia, a Computerhope company profile, and a third-party aggregator) confirm CNET Technology as a real, documentable company, with its founding year given inconsistently as 1987 or 1989. That, combined with two separately-registered OUI blocks under matching Taiwan/San Jose addresses, is enough substance to move this past a bare single-OUI shell registration.

Whether the company is still operating is unresolved. A live fetch of its site, cnetusa.com, refused the connection on 2026-08-08, and a secondary source says the site and phone line stopped working in February 2023 — both point toward defunct. A separate, lower-reliability aggregator instead claims ongoing Taiwan operations and retail listings, with no primary sourcing; the two accounts were not reconciled.

No CNET-Technology-specific CVE, ICS-CERT, or CISA advisory turned up in an August 2026 search of NVD and general web sources — a sourced negative finding, not a gap in research. As likely-defunct legacy SOHO networking hardware, the general risk class is unpatched firmware and default credentials typical of unsupported end-of-life devices; this is a category risk, not a documented finding tied to this vendor.

A same-named but unrelated company, CNETCOM INC, is a San Jose telecom/fiber-optic services business (cnetcominc.com) that surfaces in the same searches due to name similarity. It has no OUI registry entry and no connection to either 00:08:A1 or 00:80:AD.

IEEE assignment (00

08:A1): CNet Technology Inc., Hsinchu Science Park, Taiwan [Confirmed] — the IEEE MA-L registry 0008A1

80:AD): CNET TECHNOLOGY, INC., 2199 Zanker Road, San Jose, CA, US [Confirmed] — the IEEE MA-L registry 0080AD

Registry / block size

MA-L (24-bit OUI); two independent, dedicated blocks (not a shared IEEE base) [Confirmed] — the IEEE MA-L registry 0008A1, the IEEE MA-L registry 0080AD

Registry coverage

no entries for CNET/CNet Technology found in the IEEE MA-M registry or the IEEE MA-S registry [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

HQ / country

Hsinchu Science Park, Taiwan (00:08:A1) and San Jose, CA, US (00:80:AD) — two registered addresses under related company names [Confirmed] — the IEEE MA-L registry 0008A1, the IEEE MA-L registry 0080AD

Founding year

given inconsistently as 1987 or 1989 across sources [Likely] — en.wikipedia.org/wiki/CNet_Technology, computerhope.com/comp/cnet_technology.htm

Company status

unresolved/conflicting — live site connection refused 2026-08-08 and a secondary source reports the site/phone stopped working February 2023 (pointing to defunct), while an aggregator claims ongoing operations (unreconciled)

Device types

Ethernet NICs/switches, wireless/broadband routers, Wi-Fi adapters, ADSL modems, media converters, IP cameras [Likely] — en.wikipedia.org/wiki/CNet_Technology, computerhope.com/comp/cnet_technology.htm

Registration dates

Unknown for both OUIs — IEEE's the IEEE MA-L registry publishes no date field, so none is recorded or invented [Confirmed] — the IEEE MA-L registry 0008A1, the IEEE MA-L registry 0080AD

Shared-base check

neither 00:08:A1 nor 00:80:AD is one of the shared IEEE-administered bases (e.g. 70:B3:D5, 8C:1F:64); both are wholly-owned dedicated blocks [Confirmed] — the IEEE MA-L registry 0008A1, the IEEE MA-L registry 0080AD

Security context

no CNET-Technology-specific CVE or advisory found as of an August 2026 NVD/web search [Unknown, negative finding]
