Techxplorer's Ping Recorder is a WordPress plugin that makes it easier to access your server at home. The plugin provides similar functionality to a dynamic DNS service.
Each time a special 'ping' URL is called, the IP address of the request is recorded. The IP address is then used to construct a link back to your server so that you can access it via SSH.
The plugin is developed on my GitHub repository
More information on the plugin, including installation instructions and screenshots, is available on the WordPress plugin page.
