Dynamic DNS Server

Upload this script to any PHP-enabled webspace and let FritzBox call it. It will work with other DynDNS-Clients as well.

Usage

Upload everything to your webspace
(you may want to hide data.json and ip.template.html from your webroot)
Update the config section in update.php
Update your Dynamic DNS FritzBox settings
If you want to broadcast the new IP to other services (e.g. your domain registrar or whatever) look for @todo and implement it here
