ARecordUpdater is an application that automatically updates A-Records for certain hosts. This update client keeps your hostname’s IP address up-to-date. If you have a dynamic IP address which changes periodically (monthly, weekly or even daily), then this can make it difficult or impossible to connect to services at home, like remote desktop or FTP.

Using ARecordUpdater allows you to make sure you can always reach your home network, because it makes sure that your hostname is always up-to-date with the latest IP address. The update client can be run using a cron job to automate the process. So once you have it properly configured you don’t have to worry about it; you only need to remember your hostname to reach your files and services.

Supported hosts


ARecordUpdater doesn’t use its own timer. It’s better to use a cron job, so it uses less memory.
