Shanghai High-Flying Electronics Technology Co., Ltd — 9 prefixes (MA-L)

Shanghai High-Flying Electronics Technology Co., Ltd holds nine MA-L blocks in the IEEE registry, spread across three slightly different spellings of its own name and two street addresses in Pudong, Shanghai — the kind of registration drift typical of a real company re-filing over several years rather than a bare single-block shell. Independent corroboration comes from outside the MAC-vendor lookup ecosystem entirely: the FCC grantee code 2ACSV, used across dozens of Wi-Fi/BLE module filings, resolves to "High-Flying Electronics Technology Co., Ltd." at the same Longdong Avenue, Pudong address as several of the OUI registrations. Public product listings (made-in-china.com, globalsources.com) and manuals describe named embedded Wi-Fi and Wi-Fi+BLE serial-module product families — HF-LPB, HF-LPT6200/220/230/262, HF-LPX30/70, HF-A21, EW40B — aimed at OEM integration into industrial control, smart metering, smart home, and general IoT/M2M hardware, not at end-user routers. A possibly related but unconfirmed registrant, "Hi-flying electronics technology Co.,Ltd" (AC:CF:23), was also found and is flagged rather than merged.

IEEE assignment

9 MA-L prefixes → "Shanghai High-Flying Electronics Technology Co., Ltd" (3 name-spelling variants) [Confirmed] — the IEEE MA-L registry (cached IEEE MA-L snapshot)

Prefixes

34:EA:E7, E8:FD:F8, 28:9C:6E, 40:2A:8F, D4:27:87, 98:D8:63, F0:FE:6B, 00:A6:2B, 74:E9:D8 — all MA-L, none found in MA-M (the IEEE MA-S registry) or MA-S (the IEEE MA-M registry) [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L (24-bit OUI); 9 confirmed blocks under this org [Confirmed] — the IEEE MA-L registry

Org name variants

Company status

active — Likely, inferred from ongoing FCC filings and current commercial listings; no explicit corporate-status filing checked [Likely] — https://fccid.io/2ACSV, https://www.made-in-china.com/showroom/hf-sophia

Independent corroboration

FCC grantee code 2ACSV, used in dozens of Wi-Fi/BLE module filings, is assigned to "High-Flying Electronics Technology Co., Ltd." at the Longdong Avenue, Pudong address — a source outside the MAC-vendor lookup database ecosystem

[Confirmed] — https://fccid.io/2ACSV, https://fcc.report/FCC-ID/2ACSV-HF-LPT220

Device types

embedded Wi-Fi / Wi-Fi+BLE serial-to-UART modules for OEM/IoT integration, not end-user routers [Likely] — https://www.made-in-china.com/showroom/hf-sophia, http://www.hi-flying.com/

Company history (founding ~2009–2011, Shanghai HQ + Shenzhen sales office, Baidu Series A funding July 2014)

drawn from secondary aggregator profiles, not a primary filing [Likely] — https://iotglobalnetwork.com/companies/single/id/1583/shanghai-high-flying-electronics-technology-co-ltd

Website

hi-flying.com is cited as the vendor's own site in secondary sources, but a direct fetch failed with a TLS handshake error during research — access unverified [Unknown] — http://www.hi-flying.com/

Allocated date

Unknown / not applicable — IEEE publishes no registration date for MA-L assignments; the IEEE MA-L registry has no date column for any of the 9 blocks [Unknown] — the IEEE MA-L registry

Security context

Unknown — no vendor-specific CVE or advisory found for the HF-LPB/HF-LPT/HF-LPX module lines [Unknown]

Related vendors

"Hi-flying electronics technology Co.,Ltd" (AC:CF:23) — near-identical name, possibly the same company, relationship unconfirmed [Unknown] — the Wireshark manufacturer database

Analyst note

multiple OUI re-registrations plus an FCC-grantee-code cross-check independent of MAC-vendor databases together establish this as a genuine embedded-module manufacturer, not a bare shell registration; product-specific claims lean on secondary aggregator sources and should be treated as Likely rather than Confirmed.
