For my Internet connection I use a Motorola Electrify Android phone USB tethered to my desktop computer Windows XP. My service provider is US Cellular.
I would like to know the IP address of my desktop computer so that some friends in the outside world can connect to it, like for FTP and TelNet and Remote Desktop Sharing. My phone shows an IP address (it's currently 10.244.3.92, and I realize that this will change with every power-up.)
I've been told that this is the IP address I should use, but I have not been able to make any connection to my desktop computer from outside.
