So using this cmd command you can view their ip.

Usually the port number is "4443" and i noticed sometimes it doesn't work so i am guessing it is because that the person has a firewall. So here is the script.

open notepad and enter the following:

@echo.
@color 09
@netstat -n
@echo.
@pause

then save as "GetIp.cmd" and when opened you will view all established connections. And here is the rest of it.
