VNPT Technology — 3 prefixes (MA-L)

A MAC address starting with A4:F4:C2, A0:65:18, or D4:9A:A0 belongs to VNPT Technology, the electronics-manufacturing arm of Vietnam Posts and Telecommunications Group (VNPT), and typically appears on the company's broadband customer-premises equipment — most often GPON/XGS-PON optical network terminals.

IEEE's registry lists exactly three MA-L blocks under the exact registrant name "VNPT TECHNOLOGY," all addressed to Hoa Lac Hi-Tech Park in Hanoi, Vietnam. No MA-M or MA-S sub-allocations exist under this name, so all three are dedicated /24 blocks rather than shares of an IEEE-administered pool.

The company's product line is broad for a single OUI holder: GPON/XGS-PON ONTs and OLTs, mesh Wi-Fi, 5G/FWA and enterprise Wi-Fi gear, ADSL modems, LTE routers and MiFi hotspots, IPTV/OTT set-top boxes, smart-home cameras, and smartphones, unified under a device-management layer branded "ONE Telco Platform."

A separate, already-documented IEEE registrant — Vietnam Post and Telecommunication Industry Technology Join Stock Company — holds five more MA-L blocks at the identical Hoa Lac Hi-Tech Park address. IEEE's registry does not link the two name strings, but the shared address and matching corporate branding make it likely the same manufacturer registered twice, not a duplicate-slug artifact.

No CVE or security advisory naming VNPT Technology hardware is on record as of an August 2026 search, though a direct NVD query could not be completed due to a site-rendering limitation — an open gap, not a confirmed clean record. The broader GPON-ONT device category has disclosed vulnerabilities in other, unrelated vendors' products.

IEEE assignment

3 prefixes (A4:F4:C2, A0:65:18, D4:9A:A0) → VNPT Technology, registered Hoa Lac Hi-Tech Park, Hanoi, Vietnam [Confirmed] — the IEEE MA-L registry assignments A4F4C2, A06518, D49AA0

Registry / block size

MA-L (24-bit OUI); 3 dedicated IEEE assignments under the exact registrant name "VNPT TECHNOLOGY," no MA-M/MA-S blocks found under this name [Confirmed] — the IEEE MA-L registry; the IEEE MA-M registry; the IEEE MA-S registry. NOTE: IEEE's public OUI data publishes no assignment/registration date; maclookup.app's per-prefix "registered" dates are third-party database artifacts, not IEEE facts, and must not be published as IEEE dates.

A4:F4:C2, A0:65:18, D4:9A:A0 [Confirmed] — the IEEE MA-L registry; maclookup.app (independent third-party corroboration of the identical 3 prefixes)

Related vendors

Vietnam Post and Telecommunication Industry Technology Join Stock Company — separate IEEE registrant-name string (5 MA-L: B8:29:03, 7C:7B:68, 4C:12:E8, CC:71:90, C4:2C:7B) at the identical Hoa Lac Hi-Tech Park address; likely the same real-world manufacturer, though IEEE's registry does not itself link the two strings

[Likely] — /mac/vendor/vietnam-post-and-telecommunication-industry-technology-join-stock/

Security note

no CVE or advisory naming VNPT Technology hardware/firmware is recorded as of an August 2026 search; a direct NVD query returned only the site's search shell rather than a results list, so this is a sourced open gap, not a confirmed clean record [Unknown] — nvd.nist.gov (query inconclusive)

Analyst note

three dedicated MA-L assignments, a live and currently-updated corporate site, and a broad vendor-published device catalogue place this well above a bare OUI-shell registration; device-type attribution to these exact 3 prefixes rests on vendor-self-published pages only, without independent FCC-ID or teardown corroboration.
