HelpIP changing tool?

You're confusing me, in your main post it sounds like you want to change your real IP. If you're asking how to change a proxy server's IP just use a different proxy. Why do you even need to change your IP for DayZ anyways?

Switching your keys would help if you can't switch IP's. Usually you get GUID/Key banned from a server. That's why switching keys would help.
But if you are IP banned, like I said you could always see if you have a Dynamic IP and see what you have to do with your router to get a new one. But if they see the same GUID they banned re-joined, they'll just keep banning you. So I suggest you switch keys.

.../too short

That's not a valid reason.
If it were you could post it in any game help section and say it's for changing servers.

He needs help?
