UPnP Tester is an experimental tool which lists all the available devices compatible with the Universal Plug-and-Play protocol including Internet Gateway Devices (IGDs). As soon as the program starts, it searches for available devices then it updates the list as devices are plugged or unplugged. The status window displays miscellaneous notifications and the IP addresses as they are assigned. You can also select a device or a service from the list and click Properties... to get some information about it or to query a service. In the properties, double-click any URL to open it in your default browser.
Universal Plug-and-Play Tester is a freeware: there is nothing to pay in order to get and use it. The Universal Plug-and-Play Tester 2.07 free full version has a size of 165 Kilobytes.
