Umm this is onld havnt try it in a while, but the way we use to do it is by sending them a file or go on video, then we go to start then click on run there we tipe command and while the file is in transfer we type in the command pront netstat -n then u will get to colums, look at the column to the right where it says on top Foreign Address look for the ip the ends with 2090 or 2091 example 12.22.43.43:2090 the ip in that case will be 12.22.43.43
But I dont know if this still works 🙂
