This is a little tool I threw together to allow my dynamic home IP to be accessible via a sub directory URL of my web server.
No warranties expressed of implied.
Place the contents of the PHP direcotry in your web accessible server location.
Build & run the C# application.
Add the Auth Code from the app to the config.inc.php
file where specified.
Add a shortcut to the C# app to your Windows startup procedure.
IP will be updated regularly as requested.
This is a simple tool that I created to serve a single purpose. It works perfectly for what I need. However if you want to fork and modify, please feel free under the MIT license. It is unlikely that I will do any further work on this.
