HiliSoft UPnP Explorer is a specialized network utility tool designed to scan, discover, and analyze Universal Plug and Play (UPnP) devices on a local area network (LAN). It serves primarily as a developer and network troubleshooting tool to inspect how smart devices broadcast themselves and interact with the network. Core Functionality
When you use the tool to discover network devices, it acts as a UPnP Control Point:
Active Scanning: The software sends out an SSDP (Simple Service Discovery Protocol) “M-SEARCH” multicast request over UDP port 1900.
Device Identification: Any active UPnP-compatible hardware on the network (such as routers, smart TVs, network printers, or media servers) responds with its presence.
XML Schema Parsing: The explorer fetches and reads the device’s XML description document. This exposes deep technical metadata, including the manufacturer name, model numbers, serial numbers, and unique IDs (UUIDs). Key Technical Insights Provided
Once discovery completes, the tool structures the network information into a hierarchical tree view, detailing:
Services: A list of all specific services the device hosts (e.g., connection managers or rendering controls).
Actions & Arguments: The exact commands the device can accept, including the required data types for those parameters.
State Variables: Real-time variables monitored by the device that reflect its current operational status. Common Use Cases UPnP Explorer – Apps on Google Play
