Hook the connec() (ws2_32) function in Conquer.exe, Read the sock_addr* parameter and then just do something like File.AppendText(socket_addr->IP); job done.
There are public tutorials on hooking this in the CO2 Programming section.
Put some work in yourself and it will pay off, you literally just have to read a guide, use the search button, dont even bother asking for a link.
Search up Microsoft Detours 2.1 on google and the first result will be elitepvpers and tell you everything you need to know to accomplish what you are doing.

Open up conquer.exe, login, open up cmd, type netstat and get the IP that way
