Jiangsu Aisida Electronic Co., Ltd — MA-L 1C:70:C9 + MA-M 64:62:66:C

The IEEE-registered holder of these blocks is Jiangsu Aisida Electronic Co., Ltd, a Chinese electronics manufacturer in Danyang, Jiangsu province. The company holds two assignments: a 24-bit MA-L (OUI 1C-70-C9, ~16M addresses) and a 28-bit MA-M (64-62-66-C block, ~1M addresses); no MA-S (OUI-36) assignment exists for it. Both registrations carry the same registry address — Aisida Industrial Park, Lanling Road, Danyang Development Zone — and the fact that the firm operates its own named industrial park, combined with the two-block footprint, points to a volume hardware operation. The specific product category, however, is genuinely Unknown: no product catalog, Alibaba or Made-in-China listing, or indexed company website (English or Chinese) could be located. A frequent data-quality trap here is name collision: three unrelated entities share a similar name — Shenzhen Aisidi Co., Ltd (a large SZSE-listed mobile-phone distributor, not an OEM), Aisida LLC of Lanham, Maryland (a one-person investment holding company), and aisida.cn (a Yingkou web-design firm). None of them is the OUI holder, and they should not be merged into this entry. No CVEs, CISA KEV entries, or public security advisories were found for the vendor; that absence reflects a low public profile rather than a confirmed clean record. Per IEEE policy, no registration date is recorded: IEEE publishes none for MAC/OUI prefixes, and the "2021-11-05" / "2019-12-20" dates shown by third-party lookup databases are scrape artifacts, not IEEE facts.

IEEE assignment (MA-L)

1C-70-C9 → Jiangsu Aisida Electronic Co., Ltd [Confirmed] — the IEEE MA-L registry (line 727), corroborated by maclookup.app / hwaddress.com

IEEE assignment (MA-M)

64-62-66-C block → Jiangsu Aisida Electronic Co., Ltd (~1M addresses) [Confirmed] — the IEEE MA-M registry (line 5539)

MA-S (OUI-36)

none found for Aisida [Confirmed] — the IEEE MA-S registry (no matching row)

Registry / block sizes

MA-L (24-bit OUI, ~16M addresses) + MA-M (28-bit, ~1M addresses); total ~17M addresses [Confirmed] — IEEE the IEEE MA-L registry / the IEEE MA-M registry

Registered address

Aisida Industrial Park, Lanling Road, Danyang Development Zone, DanYang, Jiangsu 212300, CN [Confirmed] — IEEE the IEEE MA-L registry / the IEEE MA-M registry, maclookup.app, hwaddress.com

Country

CN (China — Jiangsu province) [Confirmed] — IEEE registry address, hwaddress.com

Company status

presumed active (registrations live in IEEE files); no independent corporate-status source confirmed [Likely] — IEEE registry presence

Device types

Unknown — no product catalog or device-type corroboration in open sources; block sizes suggest a volume electronics OEM but the category is unconfirmed [Unknown] — no source

Vendor website

Unknown — no official site located in indexed English or Chinese sources (aisida.cn is an unrelated Yingkou web-design firm, not this vendor) [Unknown] — no source

Registration date

Unknown — IEEE publishes no registration dates for MAC/OUI prefixes; the "2021-11-05" (MA-L) and "2019-12-20" (MA-M) values on third-party databases are scrape artifacts, not IEEE facts [Confirmed (no IEEE date exists)] — maclookup.app (artifact dates), IEEE the IEEE MA-L registry schema

Confusable entities (do NOT merge)

(1) Shenzhen Aisidi Co., Ltd (深圳市爱施德股份有限公司, SZSE:002416) — mobile-phone distributor/retailer, not a hardware OEM; (2) Aisida LLC, Lanham MD, USA — single-person investment holding company; (3) aisida.cn — Yingkou web-design firm

[Confirmed] — linkedin.com/company/shenzhen-aisidi-co-ltd-, buzzfile.com

Security context

no CVEs, no CISA KEV entries, no public advisories found; absence reflects limited public profile, not a confirmed clean record [Unknown] — no source

Analyst note

1C:70:C9 and the 64:62:66:C MA-M range reliably identify Jiangsu Aisida hardware on a globally-administered address; the unconfirmed device category limits asset-classification specificity beyond "Chinese electronics manufacturer."
