• requests library

Setup Instructions

1. Clone the Repository

git clone https://github.com/yourusername/cloudflare-dynamic-ip-updater.git
cd cloudflare-dynamic-ip-updater

2. Install Dependencies

Install the required Python library:

pip install reqirements.txt

3. Create a Configuration File

Use the provided config.json.example as a template:

cp config.json.example config.json

Edit config.json with your details:

{
    "records": [
        {
            "api_token": "your_api_token",
            "zone_id": "your_zone_id",
            "record_name": "example.com",
            "proxied": true
        }
    ]
}

api_token: Your Cloudflare API Token with permissions for DNS Zone and DNS Records.
zone_id: The Zone ID of your domain in Cloudflare.
record_name: The DNS record (e.g., example.com or sub.example.com).
proxied: true to enable Cloudflare Proxy, false to disable it.

4. Run the Script

Run the script to start updating your DNS records:

python main.py

The script will fetch your current public IP and update the specified DNS records if the IP changes.

5. Run Continuously

To keep the script running 24/7, use a process manager like screen, tmux, or a system service.

Using screen:

screen -S ip-updater python cloudflare_ip_updater.py

Using a Systemd Service (Linux):

Create a service file (e.g., /etc/systemd/system/cloudflare-ip-updater.service):

[Unit]
Description=Cloudflare Dynamic IP Updater
After=network.target

[Service]
ExecStart=/usr/bin/python3 /path/to/cloudflare_ip_updater.py
Restart=always
User=your_username
WorkingDirectory=/path/to/repo

[Install]
WantedBy=multi-user.target

Enable and start the service:

sudo systemctl enable cloudflare-ip-updater
sudo systemctl start cloudflare-ip-updater
