Shanghai DigiVision Technology Co., Ltd. — 2 prefixes (MA-L)

Shanghai DigiVision Technology Co., Ltd. holds two IEEE MA-L blocks, 00:26:4C and 00:03:4C, registered to two different Shanghai addresses (No. 333 Guangji Rd., 200083 and 11F Heng Tong, 200050 respectively) — a pattern consistent with separate manufacturing sites, business units, or registrations filed years apart rather than a single-address shell registration. Independent third-party MAC-lookup services (maclookup.app and macvendors.com) both resolve the company name identically for each prefix, which corroborates the IEEE organization string beyond the bare registry entry. A B2B trade listing (allitwares.com) identifies the company as a manufacturer of audio/video integrated circuits, specifically citing "VGA Sensors" as a product under its "ICs for Audio/Video Applications" line — the only device/product context located, and it was not independently corroborated by a second source, so it is held at Likely rather than Confirmed. Two loose ends were checked and deliberately excluded rather than guessed at: a PitchBook snippet citing an 1999 founding date belongs to a generically-named "DigiVision Technology" that could not be confirmed as this legal entity, and a naming collision with an unrelated Taiwanese vendor "Digiever" (which does carry real CVEs and Mirai/ShadowV2 botnet coverage) was identified and is flagged here so it is never conflated with this vendor in future work.

Organization name

Shanghai DigiVision Technology Co., Ltd. [Confirmed] — the IEEE MA-L registry; cross-verified in the Wireshark manufacturer database at lines 855 and 9979

Prefixes (2, both MA-L)

00:26:4C (No. 333 Guangji Rd., Shanghai, CN 200083); 00:03:4C (11F, Heng Tong, Shanghai, CN 200050) [Confirmed] — the IEEE MA-L registry, the IEEE MA-L registry

Third-party name cross-check

identical organization name returned independently for both prefixes by two separate lookup services [Confirmed] — https://api.maclookup.app/v2/macs/00:26:4c, https://api.maclookup.app/v2/macs/00:03:4c, https://api.macvendors.com/00:26:4C:00:00:00

MA-M / MA-S assignments

none found under this organization [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

Registration/assignment date

Unknown — IEEE's public the IEEE MA-L registry publishes no date column; third-party "first registration" dates (e.g. udger.com's 2000-11-09 / 2010-01-05) are database artifacts, not IEEE facts, and are not recorded as such [Confirmed absence of an IEEE date] — https://udger.com/resources/mac-address-vendor-detail?name=shanghai_digivision_technology_co-ltd (cited only to show the artifact, not adopted)

Product / device context

audio/video integrated circuits, with "VGA Sensors" named as a specific product under "ICs for Audio/Video Applications" [Likely — single B2B listing, not independently corroborated] — http://www.allitwares.com/company/home_page.php?user_id=98920

Company status

Likely active — identifiable company name, address history, and an existing product listing, but no confirmed operating-status source (e.g. registry filing) was located [Likely] — http://www.allitwares.com/company/home_page.php?user_id=98920

Founding year

Unknown — a 1999 founding date attributed to "DigiVision Technology" on PitchBook could not be confirmed as this legal entity and is not adopted [Unknown] — https://pitchbook.com/profiles/company/97410-43 (flagged, not used)

Security history

none found tied to this vendor. Caution: an unrelated, similarly-named Taiwanese vendor "Digiever" has real CVEs (CVE-2023-52163/52164) and Mirai/ShadowV2 botnet coverage — do not conflate with Shanghai DigiVision Technology [Confirmed absence for this vendor] — https://securityaffairs.com/186021/security/u-s-cisa-adds-a-flaw-in-digiever-ds-2105-pro-to-its-known-exploited-vulnerabilities-catalog.html (cited to document the exclusion)

Website

no official company website was independently confirmed; only a third-party B2B directory listing was found [Unknown]
