How to setup Dynamic DNS for Android

If your Android device uses a dynamic IP address, you can use the ClouDNS Dynamic DNS feature to automatically keep your DNS record updated.

For this configuration, you can use the Cronjobs-web cron application for Android. The application periodically opens your ClouDNS Dynamic URL and updates the corresponding A or AAAA record with the current IP address.

How to use it?

In order to configure Dynamic DNS on your Android device, please follow the steps below:

1. Log in to your ClouDNS account and navigate to the DNS zone you want to use.
2. Find or create the A or AAAA record that you want to update dynamically.
3. Click on the Active Dynamic URL icon next to the record and activate the Dynamic URL.
4. Copy the generated Dynamic URL. Depending on the record type, it will look similar to:

   https://ipv4.cloudns.net/api/dynamicURL/?q=your-string

   https://ipv6.cloudns.net/api/dynamicURL/?q=your-string

   Note: The URLs above are only examples. You must use the Dynamic URL generated for your own DNS record.

5. Download and install the Cronjobs - web cron application from Google Play:
6. Open the application and tap the plus (+) icon in the bottom-right corner.
7. Select Standard mode to create a new cronjob.
8. Configure the cronjob with the following settings:
   • Name: Enter a name of your choice, for example ClouDNS DDNS.
   • URL: Paste the Active Dynamic URL copied from your ClouDNS DNS record.
   • Time Interval (minutes): 10
   • Time-out (seconds): 10
9. Tap ADD EVENT to save the cronjob.

That's it! The application will now periodically access your ClouDNS Dynamic URL and keep your A or AAAA record updated with the current IP address of your Android device.

Note: Cronjobs-web cron is only one option for automating Dynamic DNS updates on Android. Other automation applications, such as Automate or Tasker, can also be used. The important requirement is that the application can periodically send an HTTP GET request to your ClouDNS Dynamic URL.
