Chicony holds 5 MA-L blocks (about 83.9 million addresses) registered as "Chicony Electronics Co., Ltd." at No.25, Wugong 6th Rd., Wugu Dist., New Taipei City, Taiwan. Verified samples include 40:62:EE, 4C:BB:58, 64:5A:04, 90:7F:61, and B0:C0:90. These OUIs relate to laptop keyboards (Chicony makes a very large share of them), webcams (both integrated and standalone), power supplies, and some networking. The key analyst point is the ODM pattern with a USB twist: most Chicony keyboards and webcams are USB peripherals that do not carry a network MAC, so a Chicony OUI on a network MAC more likely reflects Chicony's networked or EMS output rather than a keyboard/webcam. A multiple-registrant note: Chicony Power Technology is a related company, though a separate Chicony Power OUI was not confirmed this pass. For triage, a Chicony OUI on a NIC is uncommon relative to its USB output — treat it as ODM-built networked hardware, not a Chicony-branded consumer product.
