Vietnam Post and Telecommunication Industry Technology Joint Stock Company (VNPT Technology) — 5 prefixes (MA-L)

This registrant is VNPT Technology, the electronics-manufacturing arm and a core member of Vietnam Posts and Telecommunications Group (VNPT), the country's state-linked national telecom operator. Its IEEE footprint is five MA-L (24-bit OUI) assignments — B8:29:03, 7C:7B:68, 4C:12:E8, CC:71:90, and C4:2C:7B — all registered to the same Hoa Lac Hi-Tech Park address near Hanoi. The registry spelling is inconsistent: four rows read "JOIN STOCK COMPANY" (an apparent IEEE typo for "Joint Stock") and one (CC:71:90) reads the correct "JOINT STOCK COMPANY," but the shared name and address confirm all five belong to a single legal entity rather than distinct companies. The devices carrying these prefixes are, per the vendor's own product catalog, GPON optical network terminals (ONTs), broadband and Wi-Fi routers/gateways, IPTV set-top boxes, and IoT/smart-home gear (ONE Home, ONE Farm) — the CPE and access-network classes VNPT and other carriers deploy. VNPT Technology states it has supplied over eight million GPON ONTs to carriers worldwide. This is a substantive, verifiable telecom-equipment OEM, not a single-OUI shell.

IEEE assignment

5 MA-L prefixes → this registrant, registered at Hoa Lac Hi-Tech Park, Hanoi, VN 100000 [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI) only; no MA-M or MA-S entries found for this org [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry (no MA-M/MA-S matches)

Verified prefixes (all MA-L)

B8:29:03, 7C:7B:68, 4C:12:E8, CC:71:90, C4:2C:7B [Confirmed] — IEEE MA-L

Registry name variants

4 rows "…JOIN STOCK COMPANY" (registry typo), 1 row (CC:71:90) "…JOINT STOCK COMPANY"; same address → same legal entity, not distinct companies [Confirmed] — IEEE MA-L

HQ / country

Hi-Tech Industrial Zone I, Hoa Lac Hi-Tech Park, Thach That, Hanoi, VN 100000 [Confirmed] — IEEE MA-L (registry address); https://vnpt-technology.vn/en/about_page/organisational-structure

Company / identity

VNPT Technology — electronics-manufacturing member of Vietnam Posts and Telecommunications Group (VNPT); founded 6 Jan 2011 [Likely] — https://vnpt-technology.vn/en/about_page/organisational-structure ; https://en.wikipedia.org/wiki/Vietnam_Posts_and_Telecommunications_Group (parent group)

Company status

active [Likely] — https://vnpt-technology.vn/ ; corroborated by EMIS / D&B / Vietnamese business-registry (dauthau.asia) profiles

Device types

GPON ONTs, broadband/Wi-Fi routers & gateways, IPTV set-top boxes, IoT/smart-home (ONE Home, ONE Farm) [Likely] — https://vnpt-technology.vn/en/solution_detail/vnpt-technology-gpon-solutions ; https://vnpt-technology.vn/vi/product_category (vendor's own product pages; no independent teardown/FCC corroboration found this pass)

No IEEE date

IEEE publishes no assignment/registration date for OUI/MAC prefixes; maclookup.app's "registered 30 July 2021" is a third-party database artifact, not an IEEE fact — not recorded [Confirmed] — https://maclookup.app/vendors/vietnam-post-and-telecommunication-industry-technology-joint-stock-company

Security context

no device-specific CVEs or advisories surfaced this pass (null result, not a clean bill of health). Note: VNPT's "Cyber Immunity" unit (sec.vnpt.vn) is a security *researcher* that has reported bugs in third-party gear (e.g. Netgear) — that is not a finding about VNPT's own devices and must not be conflated with device risk

Analyst note

OUI reliably identifies genuine VNPT Technology-manufactured CPE (globally-administered addresses); device-type breakdown rests on vendor-published product pages only, so treat specific device attributions as Likely, not Confirmed.
