I'm affraid the "damage" has already been done. Most likely nothing at all will happen.. If you're really nervous you could change your IP, if you'd like to know how I'll look up my little "guide" on how to.
Edit: Start > Run > Cmd > ipconfig/release
Now go to your network connections right click the one you use and click property now click the Internet Protocol TCP/IP and click Property. Use the following IP adress:
123.123.123.123 just hit tab and the other will be 255.0.0.0 leave it like this press Ok > Close it'll take some time untill it's loaded. Now undo everything you just did and go into
Start > Run > Cmd > ipconfig/renew - You should now have not a completely new IP.
