I've made a small communication channel with other users of my application, it will connect using TCP which I tested and worked with two instances of my application on my home PC.

I have to type in my IP address of what would be the "remote" computer i'm talking to, my issue is some of my users may not even know what their IP is to give it to me so how can I get my IP and save it as a setting to send to other users so it can be added as the PC they are talking to?
