Qingdao Goertek Horizons Tecnology Co.,LTD — 2 prefixes (MA-L)

This vendor holds two IEEE MA-L (24-bit OUI) blocks — 74:FB:17 and 04:34:C3 — both registered to the exact organization string "Qingdao Goertek Horizons Tecnology Co.,LTD" at the address "155 Zhuzhou,road Qingdao Shandong CN 266101" (the org name carries a double space and the misspelling "Tecnology," reproduced verbatim from the registry). The registrant belongs to the Goertek ecosystem: Goertek Inc. (Shenzhen-listed, 002241) is a large Chinese electro-acoustic and optical-component manufacturer and ODM based in Weifang/Qingdao, known as an acoustic-module supplier to Apple, Samsung, and Sony, and active in MEMS microphones, true-wireless earbuds, wearables, and AR/VR optical modules. It operates several legally distinct Qingdao entities, so this "Horizons Tecnology" registrant should not be merged with the separate "Qingdao GoerTek Technology Co., Ltd.," "Weifang Goertek Electronics," "Goertek Inc.," or "Qingdao Goertek Intelligent Sensor" registrations that also appear in the IEEE data. The exact corporate relationship of this specific entity to Goertek Inc. (subsidiary, joint venture, or an alternate transliteration) could not be confirmed against a primary Chinese business registry, so it is tagged Likely. Devices carrying these prefixes are most plausibly Wi-Fi/Bluetooth consumer hardware — earbuds, audio modules, wearables, or AR/VR gear — that Goertek manufactures as an ODM, but no source ties either exact prefix to a named end product, so device-type attribution is inferred only. IEEE publishes no registration date for OUI blocks, so none is recorded here; third-party "registration date" values are database artifacts, not IEEE facts.

IEEE assignment

2 prefixes → "Qingdao Goertek Horizons Tecnology Co.,LTD" (org string verbatim, incl. double space + "Tecnology" misspelling) [Confirmed] — IEEE MA-L (:30784)

Registry / block size

MA-L (24-bit OUI); 2 IEEE prefixes [Confirmed] — the IEEE MA-L registry; no MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) block exists under this exact org name

Verified prefixes (both MA-L)

74:FB:17, 04:34:C3 [Confirmed] — IEEE the IEEE MA-L registry (lines 7157, 30784); corroborated https://networklookup.com/mac/vendor/qingdao-goertek-horizons-tecnology/

155 Zhuzhou Road, Qingdao, Shandong 266101, CN (registry address; verbatim "155 Zhuzhou,road Qingdao Shandong CN 266101") [Confirmed] — IEEE MA-L

Registration date

none — IEEE publishes no assignment/registration date for OUI blocks; third-party "registration date" scrapes (e.g. 2024-10-18 / 2024-12-03 on maclookup.app) are database artifacts, not IEEE facts, and are not recorded here [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv (no date column); https://maclookup.app/vendors/qingdao-goertek-horizons-tecnology-co-ltd

Parent / ecosystem

Exact entity relationship

whether this "Horizons Tecnology" registrant is a wholly-owned Goertek subsidiary, a JV, or an alternate transliteration of another Goertek entity is Unknown — not confirmed against a primary Chinese business registry or Goertek investor disclosure [Unknown]

Device types

most plausibly Wi-Fi/Bluetooth consumer hardware (TWS earbuds, audio/speaker modules, wearables, AR/VR) manufactured as ODM — inferred from Goertek's documented product lines, not from any source tying these exact prefixes to a named product [Likely] — https://en.wikipedia.org/wiki/Goertek

Related (distinct) vendors — do NOT merge

Security context

no device-specific CVE or advisory tied to these OUIs. Parent-level only: 2025 ASPI reporting raised concerns over Goertek's funding of a UK acquisition (Plessey) — scoped to the parent company, not to devices carrying 74:FB:17 / 04:34:C3 [Likely] — https://en.wikipedia.org/wiki/Goertek

Analyst note

a globally-administered address in these blocks identifies genuine Goertek-registered hardware, but many consumer BT/Wi-Fi devices use MAC randomization, so OUI absence does not mean "not Goertek"; don't rely on OUI alone for inventory or access control.
