Aztech Electronics Pte Ltd — 3 prefixes (MA-L)

A MAC address beginning with 00:26:75, 00:30:0A, or E0:8E:3C belongs to Aztech Electronics Pte Ltd, a Singapore-based OEM/ODM manufacturer and consumer-brand vendor of telecom and networking hardware. These three IEEE MA-L prefixes are registered to the company at 31 Ubi Road 1, Singapore 408694, and typically identify ADSL/VDSL routers, DSL modems, mesh Wi-Fi systems, or ISP-branded gateways rather than a single narrow device class.

Aztech Electronics is part of the wider Aztech group (also trading as Aztech Systems Ltd and Aztech Global Ltd), incorporated in Singapore since 1986. The company operates as a contract manufacturer for the telecom/networking industry while also selling its own branded consumer products, with manufacturing support in China and distribution across more than 20 countries.

Confirmed shipped products under the Aztech name include the DSL605EU and DSL600EU ADSL2 routers, the DSL5018EN and DSL705E/DSL705EU DSL gateways, the WMB250AC mesh Wi-Fi router, and the Aztech8900 router distributed by Singapore ISP Singtel/SingNet. Multiple CVEs have been filed against Aztech router and mesh firmware, which independently confirms these devices exist and are in active use on real networks.

IEEE's public OUI registry does not publish assignment or registration dates for any of the three prefixes. Third-party lookup services (maclookup.app, macaddress.io) display dates such as 2000-11-09 for 00:30:0A, 2010-01-05 for 00:26:75, and 2014-11-11 for E0:8E:3C, but these are aggregator database artifacts, not IEEE-sourced facts, and are not recorded here as registration dates.

Registry coverage

MA-L only; no MA-M or MA-S registrations found for this registrant [Confirmed] — cached IEEE OUI registry

Registration dates

Unknown — IEEE OUI data does not publish assignment/registration dates for any prefix; third-party "registered" dates (e.g. maclookup.app: 00:30:0A 2000-11-09, 00:26:75 2010-01-05, E0:8E:3C 2014-11-11) are aggregator database artifacts, not IEEE facts [Confirmed] — maclookup.app, macaddress.io

Company identity / substance

real, decades-old Singapore electronics/networking manufacturer (Aztech group, est. 1986), OEM/ODM + own-brand consumer products; 3 separate OUI assignments across a ~14-year span and multiple CVEs against shipped firmware corroborate an operating hardware vendor rather than a bare single-OUI shell registration. Primary IEEE registry live fetch was blocked (HTTP 418 from standards-oui.ieee.org), so the company-name cross-check rests on third-party lookups plus the cached registry file, not a direct live primary-registry read.

Analyst note

three independently-registered OUI blocks plus real, CVE-documented shipped hardware place this registrant above the "bare shell" bar for OUI vendor entries — company substance is corroborated by product and security-research evidence, not just a name match.
