This is an easy program that will change your IP with one click. I realize Kyizzle has a similar thread but I think this one is easier. Note that this is not mine, and I don't know the author as this was given to me a while ago by a friend.
You can use this to get around an IP ban on a private server or to get around sites that control how many times you do something by watching your IP. Instead of masking your IP, change it completely!
This will disconnect you from the internet for about 10 seconds so don't be doing something all to important! :P

And since I'm a dirty, lazy leecher, here is the VirusTotal scan report:
I was surprised that it found 3 suspicious things, but I didn't get anything bad. You'll just have to trust a leecher, but it would help a lot if someone more known on the forums would confirm it.
Instructions are not needed as all you really need to do is enter the Connection Name and click "Go."
Hope this helps!
