2Wire Inc — 34 prefixes (MA-L)

2Wire Inc was a Silicon Valley home-networking equipment maker, founded in 1998 and headquartered in San Jose, California, that shipped high volumes of residential gateway hardware to major telcos worldwide. It holds 34 distinct MA-L (24-bit OUI) blocks, all registered to the org name "2Wire Inc," which is well beyond a bare single-prefix registration and consistent with a large customer-premises-equipment (CPE) manufacturer — so consolidating all 34 prefixes into one vendor entry is far more useful than minting near-identical per-prefix pages. Its flagship HomePortal line combined a DSL modem, router, firewall, and remote management in a single residential gateway, and its MediaPortal hardware handled IPTV/DVR duties. These devices were the CPE distributed by carriers including AT&T (U-verse), Qwest, Embarq, Windstream, Bell Canada, Telmex, BT Group, Telstra, and SingTel; by June 2008 the company reported shipping over 20 million gateways. Pace plc acquired 2Wire in July 2010 for roughly $475M, and the brand and product lines were subsequently absorbed into Arris (now CommScope). The practical implication for MAC/OUI lookup: a 2Wire OUI on a home or small-office LAN almost always indicates a telco-supplied DSL/IPTV residential gateway — most commonly ex-AT&T U-verse CPE — even years after the corporate acquisitions.

IEEE assignment

34 MA-L prefixes → 2Wire Inc, registered San Jose, CA, US [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI). No MA-M (28-bit) or MA-S (36-bit) assignments exist for this org — verified against the IEEE MA-M registry and the IEEE MA-S registry (zero matches) [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "First registration: 09 November 2000" shown by third-party tools (maclookup.app / macaddress.io) is a database scrape/index artifact, not an IEEE fact — it must not be recorded as a registration date.

HQ / country

1704 Automation Parkway, San Jose, CA 95131, US (registry address; formatting drift across filings includes a "1764" typo variant and an older "694 Tasman Drive, Milpitas, CA 95035" on the earliest-looking record, OUI 00:D0:9E — all share org name "2Wire Inc," so this is registry drift over time, not distinct companies)

Security note

2Wire gateways have named CVEs. CVE-2009-3962 — the xslt web-management handler (TCP 50001) on models 1700HG/1701HG/1800HW/2071/2700HG/2701HG-T (firmware before 5.29.52) allows an unauthenticated remote attacker to force a device reboot (DoS) via a crafted page parameter; related to CVE-2006-4523; public exploit code exists (exploit-db 7060, 10182). CSRF weaknesses in the same UI have also been reported. Separately (hygiene, not a CVE): 2Wire gateways shipped with default admin credentials on the device label.

[Confirmed] — cve.circl.lu/cve/CVE-2009-3962, exploit-db.com/exploits/7060

Analyst note

A 2Wire OUI almost always signals a telco-distributed DSL/IPTV residential gateway (frequently ex-AT&T U-verse CPE). Devices persist on networks long after the 2010 Pace acquisition and later CommScope consolidation, so the OUI remains a reliable CPE indicator even though 2Wire no longer exists as a standalone brand.
