iFLYTEK CO.,LTD. — 4 prefixes (2× MA-L, 2× MA-M)

iFLYTEK CO.,LTD. is a Chinese artificial-intelligence company (Shenzhen-listed, ticker 002230) founded in 1999 and headquartered in Hefei, Anhui, whose core business is speech recognition, natural-language processing, and computer-vision AI. In the IEEE registry the company holds four distinct MAC-prefix assignments rather than a single OUI: two full 24-bit MA-L blocks — 0C:1B:CC and 20:FF:36 — and two 28-bit MA-M blocks — D0:C8:57:D0/28 and 14:AE:85:30/28. All four list the identical registrant address, the "National Intelligent Speech High-tech Industrialization Base, No. 666, Wangjiang Road West, Hefei, Anhui, CN 230088," which is why consolidating them into one vendor entry is more useful than four near-identical per-prefix pages. Hardware bearing these prefixes is most likely iFLYTEK-brand or iFLYTEK-chipset voice gear: smart recorders (offline speech-to-text), smart translators, "Smart VoiceBook" devices, voice-enabled smart speakers, and embedded voice modules sold to OEMs. One caveat matters for any downstream page: IEEE publishes no assignment date for OUI/MA-L/MA-M blocks, so the "Date Registered" some third-party lookup tools display (e.g. maclookup.app's "13 August 2024" for 0C:1B:CC) is a database artifact, not an IEEE fact, and must be left null. The materially non-obvious trust fact is non-technical: iFLYTEK was added to the U.S. Commerce Department (BIS) Entity List in October 2019, restricting its access to U.S.-origin technology, on the stated rationale that its technology was used in surveillance of Uyghurs and other minorities in Xinjiang.

IEEE assignment

4 prefixes → IFLYTEK CO.,LTD., registered Hefei, Anhui, CN [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the Wireshark manufacturer database

Registry / block sizes

two MA-L (24-bit OUI) — 0C:1B:CC, 20:FF:36; two MA-M (28-bit) — D0:C8:57:D0/28, 14:AE:85:30/28 [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

Registered address

National Intelligent Speech High-tech Industrialization Base, No. 666, Wangjiang Road West, Hefei, Anhui, CN 230088 (identical across all four blocks) [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

No IEEE date

IEEE publishes NO assignment/registration date for these blocks; maclookup.app's "Date Registered: 13 August 2024" for 0C:1B:CC is a third-party database artifact, not an IEEE fact — leave null [Confirmed] — the IEEE MA-L registry (columns Registry/Assignment/Org Name/Org Address only); artifact per https://maclookup.app/macaddress/0C1BCC

IANA reference

not applicable (IANA has no reference for MAC/OUI vendor blocks) [Confirmed] — n/a

Security / trust context

no product-specific CVEs found for iFLYTEK hardware/firmware ("none found," not exhaustively ruled out). The standout trust fact is that iFLYTEK was placed on the U.S. BIS Entity List in October 2019 over its technology's use in Xinjiang surveillance [Likely — three corroborating secondary sources; Federal Register primary blocked by anti-bot in this pass] — scmp.com, dwt.com/insights/2019/10/us-blacklists-eight-chinese-technology-firms, cyberscoop.com/china-surveillance-companies-entity-list

CSA membership

listed member of the Connectivity Standards Alliance, no product-category/Matter specifics given on the member page [Likely] — csa-iot.org/member/iflytek-co-ltd

Analyst note

An iFLYTEK OUI on a globally-administered address identifies genuine iFLYTEK-registered hardware, but per-prefix product mapping is not established — the org-level product line is known, not which exact device ships on 20:FF:36 vs. the MA-M sub-blocks.
