7Inova Technology Limited — 1 prefix (MA-L)

A MAC address starting with 04:84:8A belongs to 7Inova Technology Limited, a Shenzhen, China-based manufacturer whose hardware most often shows up as Ethernet-over-Powerline (HomePlugAV) network adapters, though the company also ships WiFi routers, WiFi repeaters, and smart-home plugs under the same brand.

7Inova holds a single IEEE MA-L block, 04:84:8A, registered to "7INOVA TECHNOLOGY LIMITED" at an address in Longhua District, Shenzhen. No additional MA-L, MA-S (oui36), or CID (the IEEE MA-M registry) blocks were found under any 7Inova name variant, so this is the company's only known OUI assignment.

The company maintains an active corporate website (7inova.com) with detailed EoP/powerline product catalogs, alongside third-party B2B storefronts on Alibaba, Made-in-China, and TradeWheel, and a LinkedIn company page — enough independent corroboration to identify 7Inova as an operating hardware manufacturer rather than a bare shell registration, even though it holds only one OUI block.

Confirmed product lines include HomePlugAV powerline adapters (some PoE variants), a "Security Powerline Network Adapter" line marketed for NVR/CCTV installs (e.g. the AV600), industrial/IoT powerline modules, a wall-mount WiFi travel router (model 7R1522), a WiFi range repeater (model 7W211), and smart plugs.

No CVE or 7Inova-specific security advisory is recorded as of an August 2026 search. An independent write-up on HomePlugAV powerline security lists a rebranded 7HP120 unit among many vendors' adapters sharing a proximity-based physical-access weakness in the HomePlugAV standard itself — a protocol-wide issue, not a defect specific to 7Inova.

Registration date note

maclookup.app displays "20 June 2013" (first registered) and "01 July 2017" (updated) for 04:84:8A; these are third-party database artifacts, not IEEE facts — IEEE's MA-L registry publishes no assignment or update date [Confirmed] — the IEEE MA-L registry, maclookup.app

Security note

No CVE recorded for 7Inova products as of an August 2026 search; a rebranded 7HP120 unit appears in independent research on a HomePlugAV protocol-wide proximity-access weakness affecting many vendors, not specific to 7Inova [Likely] — bentasker.co.uk

Related vendors

none identified [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

Analyst note

A MAC starting 04:84:8A reliably identifies 7Inova hardware, since the company holds a single, exclusively-owned MA-L block; confirmed product lines point to a HomePlugAV powerline adapter, WiFi router/repeater, or smart plug as the most likely device class.
