ALL Winner (Hong Kong) Limited — 4 prefixes (MA-L)

ALL Winner (Hong Kong) Limited holds four confirmed MA-L OUI blocks — 80:74:84, 6C:B0:77, 38:2A:8C, and 50:3A:0F — all registered to the identical organization name and Mongkok, Kowloon address in IEEE's public the IEEE MA-L registry. Unlike a bare single-block registrant, this is a real, currently active Hong Kong legal entity: the Companies Registry lists it under CR number 1385249 / BR 51335755, incorporated 28 October 2009, status Live, with an annual return filed as recently as December 2025 — the Chinese legal name (roughly "Quan Sheng (Hong Kong) Limited") does not match Allwinner Technology Co., Ltd's Chinese name, and the registered addresses differ, so this is a distinct registrant from the already-DONE vendor-allwinner (Zhuhai, Guangdong) entry despite the similarity of the English names. Repeat paid IEEE assignments across four separate blocks, plus a verifiable, currently-Live company registration, are substance signals beyond a bare shell — but targeted searches for a company website, product literature, a brand name, or any device-type corroboration for these specific prefixes turned up nothing. Device types and business activity therefore stay Unknown rather than guessed; no security advisories or CVEs were found for the vendor or its prefixes, but that absence was not checked against a dedicated CVE database and is not asserted as a clean record.

IEEE assignment

four prefixes → ALL Winner (Hong Kong) Limited, Unit No.1301, 13F, Sunbeam Plaza, 1155 Canton Road, Mongkok, Kowloon, Hong Kong, CN 999077 [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L (24-bit OUI) × 4 blocks (80:74:84, 6C:B0:77, 38:2A:8C, 50:3A:0F) [Confirmed] — the IEEE MA-L registry

No MA-M / MA-S registrations

the IEEE MA-M registry and the IEEE MA-S registry contain no matching org for this vendor; only unrelated companies share "Winner" as a substring (Bulat Co. Limited at a "WINNER BUILDING" address, "Legend Winner Limited", "WINNERS DIGITAL CORPORATION")

[Confirmed] — the IEEE MA-M registry; the IEEE MA-S registry

HQ / country

Unit No.1301, 13F, Sunbeam Plaza, 1155 Canton Road, Mongkok, Kowloon, Hong Kong [Confirmed] — the IEEE MA-L registry

Company status

active — Hong Kong Companies Registry lists CR 1385249 / BR 51335755, incorporated 28-Oct-2009, status Live, annual return filed Dec 2025 [Likely] — https://www.ltddir.com/companies/all-winner-hong-kong-limited/

Not the same registrant as vendor-allwinner

Chinese legal name and registered address differ from Allwinner Technology Co., Ltd (Zhuhai, Guangdong), which already covers 6 separate MA-L prefixes as a DONE entry; no corporate-affiliation source links the two despite the similar English name

[Likely] — https://www.ltddir.com/companies/all-winner-hong-kong-limited/; https://en.wikipedia.org/wiki/Allwinner_Technology

Device types

Unknown — no vendor website, product page, or third-party device report found for any of the 4 prefixes despite targeted searches [Unknown]

Notable products

Unknown — no product literature or brand name identified [Unknown]

Verified sample prefixes

80:74:84, 6C:B0:77, 38:2A:8C, 50:3A:0F (all MA-L, same org/address) [Confirmed] — the IEEE MA-L registry

Registration date

Unknown / not applicable — IEEE's the IEEE MA-L registry publishes no assignment/registration-date field (columns are Registry, Assignment, Organization Name, Organization Address only); third-party per-prefix "Registration Date" values seen on maclookup.app are database-scrape artifacts, not IEEE facts, and are not recorded here

[Confirmed absence] — the IEEE MA-L registry

Security context

no adverse CVE/abuse findings surfaced in general web search, but not checked against a dedicated CVE database [Unknown]

Related vendors

vendor-allwinner (Allwinner Technology Co., Ltd, Zhuhai) — separate registrant, do not conflate [Confirmed] — this site's own enrichment records

Analyst note

four independent MA-L blocks plus a verifiable, currently-Live Hong Kong company registration establish enough substance to finalize as a consolidated vendor entry rather than treat as a bare single-OUI shell, but the total absence of product/device corroboration keeps device_types and business_activity Unknown and holds overall confidence at Medium rather than High.
