Link your private IP to a domain
Normally, the IP address of your internet connection at home or in the office changes regularly. With Dynamic DNS (DDNS), you can configure a subdomain (e.g., nas.yourdomain.ch) to automatically point to your current IP. This allows you to reach your devices worldwide without having to know the IP.

Step 1: Create a DDNS domain in cPanel
- Navigate to Domains -> Dynamic DNS.
- Click on "Create".
- Enter a subdomain (e.g.,
home) and select your domain. - Add a description (e.g., "Office Server") and click "Create".
After creation, you will receive a unique Webcall URL. This URL is the "key". As soon as your device (router/NAS) calls this URL, cPanel recognizes your location's current IP and updates the DNS record immediately.
Step 2: Configure your router or NAS
For synchronization to work, your device must execute the webcall regularly. Most modern routers (like FRITZ!Box) or NAS systems support this.
curl -s https://yourdomain.ch/cpanelwebcall/YOUR_SECRET_CODEFor specialized hardware, you can find manufacturer instructions here:
Security & SSL
We strongly recommend handling the connection via HTTPS. In the DDNS table, you can click on "View SSL Certificate". If your device requires certificate verification, you can copy the details there.
Actions & Management
Via the "Actions" menu in the table, you can:
- Recreate URL: If your webcall code has been compromised.
- Delete: Permanently removes the DDNS function for this domain.
