Hi guys,
This is a simple tool I found ages ago. Recently people have been looking for something similar so I thought I'd share it with you all.
EDIT 19Nov2015 - Confirmed still working 5.22 patch
NOTE* If you run this when a LoL game is not open it will crash - don't worry this is normal. Once a game is loaded or in the loading screen you can run this tool to find the IP address of the game you are in.
This tool only finds the IP of the game, it does not and can not give you the IP address of particular players.
GLHF - don't drop my games though you bastards!
