Le Shi Zhi Xin Electronic Technology (Tianjin) Limited — 5 prefixes (MA-L)

Le Shi Zhi Xin Electronic Technology (Tianjin) Limited (乐视致新电子科技（天津）有限公司, "Leshi Zhixin") holds five MA-L OUI blocks — D4:B1:69, C8:0E:77, E0:A8:B8, B8:FC:9A, and B0:1B:D2 — all registered in China. Founded in February 2012, the company was the hardware-manufacturing subsidiary of LeTV / Le.com (later LeEco), the streaming-and-devices conglomerate started by Jia Yueting. It built Android-based smart TVs sold under the "Leshi SuperTV" / LeEco brand, alongside set-top boxes, hard-disk media players, sound bars, and gaming peripherals such as the LEGFS-201 wireless arcade joystick; smart-TV shipments reached roughly 10 million units by the end of 2016. Four of the five blocks carry the Beijing corporate/IP address (Le Shi Building, No.105 Yaojiayuan Road, Chaoyang District), while C8:0E:77 lists the Tianjin eco-city Animation Building production address, reflecting the split between the registered HQ and the manufacturing site. The practical caveat for network work is that LeEco's financial collapse in 2016–2018 ended firmware support for most models around 2018; the subsidiary was renamed Xin Leshi Zhijia in December 2017 and parent Le.com was delisted from Shenzhen in May 2020. Any of these devices still on a network should be treated as permanently unpatched Android IoT endpoints — they may also attempt to reach cloud back-ends (video, app, partner services) that are now defunct or reassigned. No vendor-specific CVEs surfaced in public databases during this pass, so named-CVE risk is Unknown rather than confirmed-clean.

Founded

February 7, 2012 [Confirmed] — en.wikipedia.org/wiki/Leshi_Zhixin

Parent company

LeTV / Le.com (later LeEco), founded by Jia Yueting; Sunac China took a significant stake in 2017; subsidiary renamed Xin Leshi Zhijia (新乐视智家) in December 2017; Le.com delisted from Shenzhen exchange 14 May 2020 [Confirmed] — en.wikipedia.org/wiki/Leshi_Zhixin, en.wikipedia.org/wiki/LeEco

Device types

Android smart TVs ("Leshi SuperTV" / LeEco), set-top boxes, hard-disk media players, sound bars, gaming peripherals (e.g. LEGFS-201 wireless arcade joystick, FCC ID 2AFOYLEGFS-201); ~10M TV units shipped by Dec 2016 [Confirmed] — en.wikipedia.org/wiki/Leshi_Zhixin, usermanual.wiki LEGFS-201

Company status

effectively defunct as the original LeEco/Le.com entity (parent delisted 2020; Jia Yueting filed US bankruptcy 2019; renamed Xin Leshi Zhijia 2017); no active product line or support confirmed as of 2026 [Confirmed] — en.wikipedia.org/wiki/Leshi_Zhixin, en.wikipedia.org/wiki/LeEco

Allocated date

Unknown — IEEE publishes no OUI/MAC registration date; a third-party "16 March 2016" date for E0:A8:B8 (maclookup.app) is a database artifact, NOT an IEEE fact, and is not recorded as allocated_date [Unknown] — IEEE the IEEE MA-L registry (no date column)

Security context

no LeEco/Leshi Zhixin-specific CVEs found in public databases this pass (named-CVE risk Unknown). General posture: these Android smart TVs / set-top boxes are recognised IoT network-ingress points; with support ended ~2018, treat any on-network as permanently unpatched Android IoT endpoints that may call defunct cloud back-ends

Analyst note

a globally-administered Le Shi Zhi Xin OUI on a device identifies genuine LeEco-era hardware; given the vendor's collapse, classify these as legacy, unsupported, unpatched Android IoT for asset-management and segmentation purposes.
