CJ intelligent technology LTD. — MA-L OUI registrant (Taiwan)

CJ intelligent technology LTD. is an IEEE MA-L registrant holding multiple 24-bit OUI blocks, each covering roughly 16.7 million addresses. The registry classification is MA-L (the large OUI block), and the assignment surfaces in the IEEE MA-L file (the IEEE MA-L registry) — not in the MA-M or MA-S tiers. The registry record places the organization at 4F, No. 16, Zhongxin St., Shulin District, New Taipei City, Taiwan, so the country is TW. Beyond the registry facts, this is a low-data vendor: no vendor website, product line, or device category could be corroborated from open sources, and no CVEs, advisories, or threat-intelligence reports reference the company name or its OUI prefixes. The naming pattern is consistent with an East Asian consumer-electronics or IoT OEM, but no specific device class is confirmed, so device type stays Unknown rather than inferred. As always with OUI data, IEEE publishes no assignment dates; any "date registered" shown on third-party MAC lookup sites (maclookup.app surfaces 2025-11-11, 2026-02-02, 2026-06-19 for these blocks) is a database-ingest artifact from when those sites scraped the public file, not a first-party IEEE fact, and is not recorded here. The registry registrant address is a first-party fact and is recorded; speculative company identity (e.g. similarly named Alibaba sellers) is not.

IEEE assignment

org name "CJ intelligent technology LTD.", registered Shulin Dist., New Taipei City, TW [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI; ~16.7M addresses per block) [Confirmed] — IEEE MA-L; not present in the IEEE MA-M registry (MA-M) or the IEEE MA-S registry (MA-S)

OUI prefixes

88:3B:DC and 84:1D:E8 confirmed in the local MA-L registry; a third block 14:B6:EB is reported by maclookup.app under the same registrant but is not present in the local the IEEE MA-L registry snapshot [88:3B:DC, 84:1D:E8 Confirmed; 14:B6:EB Likely] — the IEEE MA-L registry; https://maclookup.app/vendors/cj-intelligent-technology-ltd

HQ / country

4F, No. 16, Zhongxin St., Shulin Dist., New Taipei City, TW 238035 (registry address); country TW (Taiwan) [Confirmed] — IEEE MA-L. NOTE: the W1 web angle reported country as Unknown (it did not surface the registry address), but the first-party IEEE registry record carries the Taiwan address, so country is Confirmed from the registry.

Company status

Unknown — no corporate registry, filing, or status corroboration found in open sources [Unknown]

Device types

Unknown — no product category, device class, or product line corroborated from any source; name is consistent with a consumer-electronics/IoT OEM but no device class confirmed [Unknown] — no vendor site or product listing found

Vendor website

Unknown — no website listed in the IEEE OUI record or found via web search for this exact registrant name [Unknown]

Security context

no CVEs, advisories, or threat-intel reports reference "CJ Intelligent Technology" or the prefixes 88:3B:DC, 84:1D:E8, 14:B6:EB as of June 2026 [Confirmed (no findings)] — https://www.cvedetails.com/vendor/3012/CJ.html

Registration date

Unknown — IEEE publishes no OUI assignment dates; third-party "registered" dates (maclookup.app: 2025-11-11, 2026-02-02, 2026-06-19) are database-ingest artifacts, not IEEE facts, and are not recorded [Unknown by design]

Analyst note

low-data vendor. A globally-administered address in these blocks identifies hardware from this registrant for asset classification, but the vendor's products, website, and corporate status are unverified — treat any device-type attribution as unconfirmed.
