Automate Your Namecheap Dynamic DNS Updates
detail.loadingPreview
Effortlessly keep your Namecheap Dynamic DNS records up-to-date with this automated n8n workflow. Ensure your domain always points to your current IP address without manual intervention.
About This Workflow
This n8n workflow automates the process of updating your Dynamic DNS records with Namecheap. It's designed to periodically check your public IP address and, if it has changed, update the specified subdomains associated with your Namecheap domain. By leveraging n8n's robust automation capabilities, you can ensure that your services remain accessible even if your IP address fluctuates. The workflow is triggered at a set interval, fetching your current IP, comparing it against previously recorded IPs, and then sending the update to Namecheap if a change is detected. This is an essential tool for anyone managing dynamic IP connections for their servers or home networks.
Key Features
- Automated IP Detection: Automatically fetches your current public IP address.
- IP Change Detection: Intelligently compares your current IP with the last known IP to avoid unnecessary updates.
- Multi-Subdomain Support: Easily configure and update multiple subdomains with a single workflow.
- Scheduled Updates: Runs at a user-defined interval (defaulting to every 15 minutes) for continuous synchronization.
- Secure Credential Handling: Stores your Namecheap DDNS password securely.
How To Use
- Configure Cron Trigger: Set the
Cronnode to run the workflow at your desired interval (e.g., every 15 minutes). - Get Public IP Address: The
Get Public IP addressnode automatically fetches your current public IP. - Check for IP Changes: The
Checks IP if newfunction node compares the new IP with the previously stored IP. It only proceeds if the IP has changed. - Set Domain Credentials: In the
yourdomain.comnode, replace'yourdomain.com'and'your-namecheap-ddns-password'with your actual domain name and Namecheap DDNS password. - Define Subdomains: Modify the
subdomainsfunction node'sfunctionCodeto list your desired subdomains. - Loop Through Subdomains: The
Loops trough Subdomain listnode prepares each subdomain for the update request. - Send to Namecheap: The
Send data to Namecheapnode constructs and sends the DDNS update request to Namecheap's API using your IP, domain, password, and the current subdomain.
