Universal Plug-and-Play Tester (UPnPTest) is an experimental tool that lists all the available devices compatible with the Universal Plug-and-Play protocol including routers (IGDs). When the program starts it first checks the configuration of the required UPnP services and the Windows Firewall and possibly configure them for you (after being prompted). Then it searches for available devices and updates the list as devices are plugged or unplugged. The status window displays miscellaneous notifications and the IP addresses of the routers as they are assigned.
