If you are constantly moving between networks or IP addresses, you'll know how annoying it is to keep reconfiguring your connection settings. This usually involves constantly opening the Network and DialUp Connections applet to manually change the TCP/IP settings to match your current network.
Since the download is a Windows Installer 2.0 "Install From Web" application, it's best to select "Run from current location" on the download dialog as what is downloaded is simply the bootstrap portion of the install. IpManager works by automatically recording the configuration settings of every network you connect to. So basically, next time you work on that network, all the TCP/IP, DNS and Gateway will be ready to go next time you work on that network.
