IP Logger

I've been recently helping my friend play competitive games by booting enemy players offline for a higher chance at a win, but it's a lot of work to try and get IP's through doxxing and finding resolvable Skype accounts linked to those people. I have an extremely low success rate using this method, and I was wondering if it's possible to make an in-game IP logger of sorts, or if one already exists that I've yet to come across. Thanks.

This is not hard to find what so ever . Look on google for some ip loggers theres plenty you'll thank me in the long run :C

"In-Game IP Loggers" won't work in competitive games because they are on Valve servers. You need administrator access to the server to access other players connection info. However I would be glad to collab and make an easier VBS program for said "Resolving and Doxxing"
::EDIT::
You can get the other player steam ID by typing "status" in the console. From there, add them on steam (or don't, not sure if you can do this without adding them though) and "Voice call" them through the steam chat. It will directly connect you to them and won't pass through steam server. You can then use commview or wireshark to get their IP.
