MAC address vendor

A-TEC Subsystem INC. — 00:16:67 (MA-L)

Primary prefix
00:16:67
Block
MA-L

Summary

// what this is
A-TEC Subsystem is registered to MAC prefix 00:16:67 in the IEEE OUI database. When a device's MAC address begins with 00:16:67, that block was registered by A-TEC Subsystem — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
00:16:67 identifies genuine A-TEC Subsystem hardware, most plausibly network storage/peripheral devices or ccHDtv DVR/IP-camera equipment per the vendor's own declared catalog; no independent device teardown confirms a specific model against this prefix.

About this vendor.

Updated  ·  Confidence: High  ·  6 sources  ·  How this page is checked

A MAC address beginning with 00:16:67 belongs to A-TEC Subsystem INC., a Taiwan-based OEM/ODM manufacturer, and is typically seen on network storage devices, external drive enclosures, or DVR/IP-camera security equipment that the company builds for other brands.

A-TEC Subsystem INC. was founded in 1996 and is based in Xizhi District, New Taipei City (formerly Shijr City) — the same address IEEE lists for the 00:16:67 registration. Only one MA-L block, 00:16:67, is assigned to this company across the IEEE MA-L registry, the IEEE MA-S registry, and the IEEE MA-M registry registries.

The company's declared product lines split into two groups: computer peripherals — external HDD/optical-drive enclosures, HDD docks, card readers, USB peripherals, and network storage devices — built as OEM/ODM for clients including Philips, Acer, and Shuttle; and ccHDtv DVR/IP-camera security systems. No independent teardown ties a specific model to this prefix, so device attribution rests on the vendor's own declared catalog rather than an outside report.

A third-party aggregator lists 2005/2015 dates for this OUI, but IEEE's own registry publishes no assignment date, so those figures are a database artifact rather than an IEEE fact. No CVE or malware association for A-TEC Subsystem is recorded as of an August 2026 search.

Third-party date caveat
maclookup.app lists a "registered" date of 2005-11-06 and a last-update of 2015-11-17 for this OUI; IEEE's own the IEEE MA-L registry publishes no assignment/registration date, so these are a third-party database artifact, not an IEEE fact, and are not carried into this entry as a registration date

Security context
no CVE or public vulnerability disclosure naming A-TEC Subsystem (or close variants), and no malware/botnet association for this vendor or the 00:16:67 prefix, recorded as of an August 2026 search [Likely] — general NVD/CVE and web search, no single citable negative-result page
Shared-base check
00:16:67 is a standard, non-shared MA-L block assigned solely to A-TEC Subsystem INC.; it is not one of the IEEE-held shared /24 bases (e.g. 70:B3:D5, 8C:1F:64) sub-allocated across many unrelated companies [Confirmed] — the IEEE MA-L registry 001667
Website
no independently verified official company domain found; only third-party trade-directory listings (GlobalSources, asmag.com, Kompass, Panjiva) were located [Unknown]
Related vendors
none identified [Unknown]
Analyst note
00:16:67 is a single-OUI registrant with real, corroborated company substance — a Taiwan OEM/ODM manufacturer with a documented product catalog spanning storage/peripheral hardware and DVR/IP-camera security systems — rather than a bare, empty IEEE registration.
