Update Google Domain's Dynamic DNS on Windows with batch files

README.md

Configuration

• The reason to exist the HideBat.vbs is to hide the cmd prompt when it runs.
• You can change the frequency when this script will be run in the scheduler.bat file.
• Update the updateip.bat with your USERNAME and PASSWORD from the Dynamic DNS section in your Google Domains' DNS page. Also replace the PUT_YOUR_HOSTNAME_HERE with the hostname you want to update.

To make it run

• Complete the configuration part.
• Make sure that all files are in the same directory.
• Run the scheduler.bat file to make it run every 5 minutes (with default config).
• If you want to run it once, just run the HideBat.vbs file.
