Eastern Asia Technology Limited — 2 prefixes (MA-L)

Eastern Asia Technology Limited holds two IEEE MA-L blocks — 00:14:71 and 00:25:D1 — both registered under the identical legal name at the same New Taipei City address, which is itself a signal of an operating manufacturer rather than a one-off registrant. The registrant address matches the publicly verifiable Taiwan address of Eastech, a Taiwan Stock Exchange-listed audio company (ticker 5225.TW) under parent Eastech Holding Limited (Cayman Islands), founded in 1971 with roughly 6,000 employees and international operations spanning Taiwan, Hong Kong, China, Singapore, Vietnam, and Denmark (subsidiary Scan-Speak A/S). Eastech's product lines — headphones, transducers, soundbars, and notably Wi-Fi/Bluetooth-connected multi-room speakers and "AI music centers" with voice-assistant and streaming support — plausibly account for the OUI blocks, since radio modules in those products are the likely MAC-consuming hardware, though no per-product FCC-ID teardown ties a specific model to either block. A related Hong Kong trading entity of the same name appears in trade directories but its exact legal relationship to the Taiwan registrant is unconfirmed. No security incidents or CVEs were found tied to this vendor in this pass.

IEEE assignment

two MA-L prefixes, 00:14:71 and 00:25:D1, both registered to "Eastern Asia Technology Limited" at 8F-1, No. 188, Baoqiao Rd., Xindian Dist., New Taipei City, TW 23145 [Confirmed] — the IEEE MA-L registry (lines 36034, 36703), cross-confirmed by the Wireshark manufacturer database (lines 5216, 9859)

Registry / block size

MA-L (24-bit OUI) x2; no matching MA-M (oui36) or MA-S (mam) blocks found for this org [Confirmed] — the IEEE MA-S registry, the IEEE MA-M registry (checked, no match)

HQ / country

8F-1, No. 188, Baoqiao Rd., Xindian Dist., New Taipei City, TW 23145 [Confirmed] — IEEE MA-L registry

Company status

active — parent Eastech Holding Limited (Cayman Islands) publicly listed on the Taiwan Stock Exchange as 5225.TW; Eastern Asia Technology Limited is Eastech's Taiwan-registered operating entity, address matches Eastech's own published correspondence address exactly

[Likely] — https://www.eastech.com/about-us, https://finance.yahoo.com/quote/5225.TW/profile/

Company background

Eastech founded 1971, ~50 years of "acoustic excellence," ~6,000 global employees including 200+ acoustics/electronics/software engineers; operations in Taiwan, Hong Kong, China, Singapore, Vietnam, and Denmark (subsidiary Scan-Speak A/S) [Likely] — https://www.eastech.com/about-us

Device types

headphones/earphones, transducers (Scan-Speak brand), home theater/soundbars, portable Wi-Fi/Bluetooth speakers, multi-room Wi-Fi speakers, "AI music centers" with Google Assistant/Alexa and Spotify/Pandora streaming — plausible source of MAC-address consumption from these OUI blocks, though no FCC-ID/teardown source ties a specific product model to either block

[Likely] — https://www.eastech.com/systems

Related entity

"Eastern Asia Technology (HK) Limited," a Kwun Tong (Kowloon) speaker/audio-equipment trading company, appears in trade directories — likely a related trading arm of the same group, but not confirmed as the same legal registrant as the OUI holder [Likely] — https://panjiva.com/Eastern-Asia-Technology-Ltd-HK/25669211, https://hk.kompass.com/c/eastern-asia-technology-hk-ltd/hk016561/

Security / CVE record

no CVEs, advisories, botnet/malware reports, or default-credential campaigns found tied to this vendor or its OUI-registered devices in this pass; consumer audio (not routers/cameras/DVRs) sits outside common IoT-botnet target classes, but absence of reports in one research pass is not proof of a clean record

[Unknown] — no source found (absence of evidence, not evidence of absence)

Assignment/registration date

Unknown — IEEE the IEEE MA-L registry publishes no assignment/registration date for either block; not fabricated. A third-party lookup tool (maclookup.app) displays "05 January 2010" / last-update "17 November 2015" for 00:25:D1, but that is a database artifact, not an IEEE fact, and is not recorded here

[Confirmed absence] — the IEEE MA-L registry; caveat source https://maclookup.app/search/result?mac=0025D1

IANA Reference

N/A — not applicable to OUI/MAC vendor registry entries; left blank rather than fabricated [Confirmed]

Analyst note

two independently-assigned MA-L blocks at the same registered address, plus a verifiable publicly-listed parent with a 50+ year operating history and Wi-Fi/Bluetooth-connected product lines, place this vendor above the single-OUI-shell threshold — appropriate for a consolidated vendor entry rather than a thin per-prefix page.
