Ok well I am trying to verify one of my servers from a site and I get this:
Error: shuffle-scape.no-ip.biz resolves to IPHERE, which does not match your ip, IPHERE.
I don't know which site you're using there, but shuffle-scape.no-ip.biz currently resolves to 126.96.36.199.
Do you know some guides to configure it with my new IP ? I have no idea.
Your individual applications should come with documentation on how to do this. In MySQL, you'll likely need to find the "my.cnf" configuration file (or at least, that's what it is called on Linux), and inside that file, you should find comments that explain how this is done. For Apache, it is "httpd.conf" or similar. XAMPP might also have its own way to allow you to change all of them at once.
