Shenzhen SEI Robotics Co., Ltd — 4 prefixes (MA-L)

A MAC address beginning D4:CF:F9, 8C:98:06, 2C:D8:AE, or F0:2F:50 belongs to Shenzhen SEI Robotics Co., Ltd, a Shenzhen-based ODM/OEM manufacturer of Android TV set-top boxes, streaming dongles, smart speakers, and WiFi/GPON gateway routers.

The company, founded 2009 per its own corporate site, is a Google-certified Android TV OEM/ODM partner (Netflix, Amazon, and Google certified) and claims 300M+ units shipped to Tier-1 telecom operators worldwide. Its product line spans OTT and hybrid set-top boxes, 4K/AV1 streaming sticks, Android TV and AIoT smart speakers, GPON/WiFi gateway routers, and smart-home light/switch controllers.

Company substance beyond a bare IEEE registration is well corroborated: a live product catalog with named partner logos (Android TV, Netflix, Disney+, Dolby, DTS, Widevine, Amlogic), a physical Shenzhen registered address, and independent trade/business listings (UN Global Compact, MWC Barcelona exhibitor roster, CSA-IOT membership) all point to the same corporate entity. Four distinct OUI assignments under the same registrant name, cross-referenced across multiple third-party MAC databases, further match the profile of an active device manufacturer rather than a one-off shell registration.

The IEEE-registered legal-name string is verified directly against the vendored IEEE OUI registry cache (the IEEE MA-L registry), the canonical source of record for this pipeline, and is confirmed for all four prefixes: D4:CF:F9, 2C:D8:AE, and F0:2F:50 register as "Shenzhen SEI Robotics Co.,Ltd"; 8C:98:06 registers as "SHENZHEN SEI ROBOTICS CO.,LTD" — an all-caps registry casing variant on the same name, not a naming discrepancy.

Third-party sites display per-prefix "registration"/"last updated" dates, but these are database artifacts of the lookup services, not IEEE-published facts, and are not recorded here as registration dates.

No vendor-specific security advisory, CVE, or breach report was found for Shenzhen SEI Robotics.

The device classes it manufactures — set-top boxes and consumer WiFi/GPON gateways — belong to a product category broadly targeted by IoT botnets (e.g. Mirai-family) when running outdated firmware or default credentials; this is a category-level risk note, not a vendor-specific finding.

IEEE assignment

4 prefixes (D4:CF:F9, 8C:98:06, 2C:D8:AE, F0:2F:50) → Shenzhen SEI Robotics Co.,Ltd, registered Shenzhen, Guangdong, CN [Confirmed] — the IEEE MA-L registry (cached IEEE OUI registry)

Registry / block size

MA-L (24-bit OUI); holds 4 known IEEE prefixes [Confirmed] — the IEEE MA-L registry; cross-referenced against maclookup.app and macaddress.io, both showing the same 4-prefix set

Special note

Third-party MAC-lookup sites display per-prefix "registration"/"updated" dates (e.g. 2014-02-25, 2022-03-12, 2025-01-17); these are database artifacts of the lookup services, not IEEE facts, and are not published as IEEE registration dates on this page

none identified [Unknown]

Analyst note

Substantive, identifiable ODM/OEM manufacturer with a live product catalog, independent trade-listing corroboration, and 4 cross-referenced OUI assignments — not a bare single-OUI shell registration. No vendor-specific CVE/incident found; STB and consumer-gateway hardware is a category generally exposed to IoT botnet risk when running outdated firmware or default credentials
