Sunplus holds 5 MA-L blocks (about 83.9 million addresses) registered as "Sunplus Technology Co., Ltd." at No.19, Innovation First Road, Hsinchu City, Taiwan. Verified samples include 00:11:05, 04:D1:68, 1C:50:1E, EC:EF:17, and FC:4B:BC. These OUIs appear on multimedia SoCs (set-top boxes, DVD/media players, toys, automotive infotainment) and microcontrollers. An important multiple-registrant note: Generalplus Technology Inc. is a separate IEEE registrant holding its own OUI(s), and Sunplus Innovation Technology Inc. is a distinct spun-off entity (mainly a USB vendor, ID 1BCF) whose IEEE OUI status is unverified — so these siblings should be tracked separately rather than merged. The key analyst point is the chipset pattern: a Sunplus OUI is a flag for a networked-media or IoT device built on Sunplus silicon, not a brand. For triage, treat a Sunplus OUI as "device built on a Sunplus multimedia SoC," and check Generalplus separately as its own registrant.

- Special note
- Multiple-registrant flag — Generalplus Technology Inc. is a SEPARATE IEEE registrant with its own OUI(s); Sunplus Innovation Technology Inc. is a distinct spun-off entity (USB vendor ID 1BCF) with unverified IEEE OUI status. A Sunplus OUI is a chipset-OUI flag for a networked-media/IoT device, not a brand. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
