Hisense Visual Technology Co., Ltd. — 11 prefixes (MA-L)

Hisense Visual Technology Co., Ltd. (海信视像科技股份有限公司) holds 11 MA-L OUI blocks registered to "HISENSE VISUAL TECHNOLOGY CO.,LTD" at Qianwangang Road 218, Qingdao, Shandong, China. The company is a publicly listed subsidiary of Hisense Group, trading on the Shanghai Stock Exchange (SHA: 600060); it was formerly named Hisense Electric Co., Ltd. and renamed in December 2019. The MA-L footprint (eleven 24-bit blocks, roughly 184.5 million addresses) lines up with high-volume consumer-electronics manufacturing: the dominant product line is smart televisions sold under the Hisense, Toshiba, and Vidda brands, alongside laser-display systems, commercial displays, digital-TV broadcasting equipment, set-top and multimedia devices, and display chips. By 2022 Hisense was the world's largest TV maker by sales volume (~18% share). For asset classification this OUI reliably marks genuine Hisense display hardware. The important security context: most of these TVs run VIDAA, a proprietary Linux-based OS developed entirely by Hisense (now the second-largest smart-TV OS globally, ~30 million sets across 180+ countries), where Hisense controls the full stack — boot chain, kernel, middleware, app store, update pipeline, and telemetry. VIDAA deploys Automated Content Recognition (ACR) through an exclusive Nexxen partnership (renewed August 2025), capturing screen images roughly every 500 ms for ad targeting; the Texas Attorney General sued Hisense over this on December 17, 2025, and a court issued the first-ever Temporary Restraining Order against a smart-TV maker, halting ACR collection on Texans. UNSW research (2024) separately found Hisense TVs accept binding requests from malicious remote controls without an on-screen alert. On the positive side, Hisense committed in 2025 to up to 8 years of VIDAA OS security updates starting with 2025 models. As with all MAC/OUI data, IEEE publishes no registration dates — any per-prefix "date registered" on third-party lookup tools is a database artifact, not an IEEE fact.

Analyst note

a Hisense OUI on a globally-administered address reliably identifies genuine Hisense display hardware; the surrounding privacy/ACR posture (VIDAA full-stack control, Texas TRO) is the operationally relevant context for fleets running these TVs.
