Fihonest Communication Co., Ltd. — 3 prefixes (MA-L)

A MAC address beginning with 04:FE:A1, 40:EF:4C, or 7C:96:D2 belongs to Fihonest Communication Co., Ltd., a Dongguan, Guangdong (China)-based manufacturer, most plausibly seen on Bluetooth radio modules built for OEM integration into mobile and portable devices rather than on a finished consumer product bearing the company's own brand.

The IEEE the IEEE MA-L registry confirms all three blocks as MA-L (24-bit OUI) assignments to "Fihonest communication co.,Ltd.": two share a registered address (Room 902, Park road, Zhixing business-building, Dongguan, Guangdong 523560, CN), the third lists a separate Dongguan address (The Frist Building, ShangKeng Industrial Zone, Changping Town). Holding three independent OUI blocks is itself a substance signal — this is not a bare single-OUI shell registration.

Product context comes from an FCC equipment-authorization filing (FCC ID 2AB2RJS-BTM256) for a Bluetooth module, model JS-BTM256, operating 2402-2480 MHz under a Single Modular Approval, filed under the same company name and the same Dongguan address as the OUI registration. Two independent third-party MAC databases (maclookup.app, uic.io) corroborate the vendor-to-prefix mapping, converging with the FCC filing on company identity and location.

Third-party MAC databases show "registered" dates for two of the three prefixes (04:FE:A1 dated 14 May 2016; 7C:96:D2 dated 2 Mar 2018) — these are database artifacts, not IEEE facts, since IEEE's public OUI data carries no assignment date. The FCC grant date for JS-BTM256 (June 4, 2014) is a genuine first-party record but is a certification date, not an OUI registration date, and the two must not be conflated. No vendor-specific security advisories or CVEs were found; that is a sourced absence of findings, not a claim of a clean record.

Special note

Third-party MAC databases show non-IEEE "registered" dates for 2 of 3 prefixes (04:FE:A1 → 14 May 2016; 7C:96:D2 → 2 Mar 2018); these are database artifacts, not IEEE facts — IEEE the IEEE MA-L registry publishes no assignment date. The FCC grant date (June 4, 2014, FCC ID 2AB2RJS-BTM256) is a genuine first-party record but must be labeled as an FCC certification date, never as an OUI/IEEE registration date.

Analyst note

Three independent MA-L blocks plus an independent FCC regulatory filing under the same company name/address clear the abstention bar for a consolidated vendor entry — this is not a bare single-OUI shell.
