Cheng Uei Precision Industry Co., Ltd. (Foxlink) — 3 MA-L + 1 MA-M prefixes

A MAC address beginning 00:1A:0E, 9C:CD:82, or E0:F5:CA belongs to Cheng Uei Precision Industry Co., Ltd., a Taiwan-headquartered electronics manufacturer that trades publicly as Foxlink (TWSE: 2392). A fourth, smaller MA-M sub-allocation, DC:76:C3:D/28, is registered to the same organization (under the registry's own "Chen Uei" spelling — see below).

Foxlink is a real, verifiable company, not a shell registrant: founded 1986, publicly traded on the Taiwan Stock Exchange, and reporting roughly 63,000 employees. Its registered HQ, No. 18, Zhongshan Rd., Tu-Cheng Dist., New Taipei City, matches the registrant address on two of the three MA-L blocks (9C:CD:82 and E0:F5:CA), and also matches the address on the DC:76:C3:D/28 MA-M sub-allocation. The third MA-L block, 00:1A:0E, is registered to a Dongguan, Guangdong (China) manufacturing address instead. The DC:76:C3 base itself is an IEEE-held /24 shared with many unrelated registrants — Foxlink holds only the single /28 sub-block beneath it, registered under the variant spelling "Chen Uei Precision Industry Co., Ltd" (the registry entry genuinely drops the "g").

Foxlink's core, self-reported business is connectors, cable assemblies, and batteries/power products sold OEM/ODM to computer, communications, and consumer-electronics makers — hardware that typically does not carry its own MAC address. Independent hardware-ID databases separately attribute USB webcams to the same corporate name via USB VID 05C8, a distinct registry from IEEE MAC OUIs, so that is corporate-identity corroboration rather than proof that these specific MAC prefixes appear in webcams.

IEEE's own OUI and MAM registries publish no assignment/registration date field. Third-party lookup tools show "Registered" dates for these prefixes, but those are database artifacts, not IEEE facts, and are not presented here as registration dates.

Analyst note

three MA-L assignments plus one MA-M sub-allocation under a consistent, address-verifiable, publicly-traded company name is substance beyond a bare single-OUI shell.
