This Python script automatically updates your Cloudflare DNS records with your current public IP address whenever it changes.
- Automatically detects IP changes: The script checks your public IP and compares it to the last recorded IP.
- Updates all 'A' type records: If a change is detected, it updates all 'A' type DNS records in the specified zone to the new IP.
- Securely stores credentials: Cloudflare API credentials are stored in a separate JSON file for security.
- User-friendly setup: The script guides you through the initial setup process, including entering your Cloudflare credentials.
- Clear logging: The script provides informative messages about its actions, such as success or failure of DNS updates.
