Shenzhen Taichi Technology Limited — 3 prefixes (MA-L)

Shenzhen Taichi Technology Limited holds three separate IEEE MA-L OUI blocks — 3C:39:A8, A4:AB:39, and B0:9C:18 — all registered under an identical legal name and address: A1710, Nanshan Cloud Technology Building, Vanke Cloud City, Liuxin Third Street, Xili Community, Xili Street, Nanshan District, Shenzhen, Guangdong 518000, China. Holding three distinct blocks under one consistent registration is a meaningful signal on its own: companies typically request additional MA-L allocations only once earlier blocks approach exhaustion, so the pattern points to genuine, ongoing device production rather than a single-registration shell. That said, independent web research found no company website, no product catalog, no device-teardown or security-research reference to any of the three prefixes, and no Chinese business-registry hit that can be confidently matched to this exact registrant near the stated Vanke Cloud City / Xili address — a large multi-tenant tech park, not a distinctive locator by itself. A same-sounding, different registrant — Taichitel Technology Shanghai Co.,Ltd. (MA-M, 90:F4:21) — is a distinct company in a different city and should not be conflated with this entry. Net: real, multi-block IEEE registration activity with no further public corroboration of the company's products, market, or security context.

Non-match flag (do not conflate)

90:F4:21 (MA-M) → "Taichitel Technology Shanghai Co.,Ltd." — different entity, different registry class, different city (Shanghai vs Shenzhen) [Confirmed] — the IEEE MA-M registry

OUI-36 (MA-S) matches

none found for this registrant [Confirmed] — the IEEE MA-S registry

Company substance note

three distinct MA-L block assignments under one consistent legal name/address indicate real, ongoing device-production activity, but this cannot be independently corroborated beyond the registry (no site, product listing, or confident business-registry match)
