🌩️ Cloudflare Dynamic DNS Updater (Multi-Account Version)

Automatically updates your public IP address across multiple Cloudflare DNS records — even across different accounts or zones — using the Cloudflare API.
Perfect for dynamic IP setups (home networks, small servers, labs, etc.) where several domains or subdomains must always point to your current IP.

🔐 Environment Variables

This version supports multiple records, even from different Cloudflare accounts.
You can define them as numbered environment variables:

Variable	Description
API_TOKEN_1	API token for record #1
ZONE_ID_1	Zone ID for record #1
RECORD_NAME_1	Full subdomain for record #1 (e.g., home.example.com)
PROXIED_1	Whether Cloudflare proxy is enabled for record #1 (true/false)
API_TOKEN_2	API token for record #2 (optional)
ZONE_ID_2	Zone ID for record #2 (optional)
RECORD_NAME_2	Full subdomain for record #2 (optional)
PROXIED_2	Whether Cloudflare proxy is enabled for record #2 (true/false)

You can add as many as you need: _3, _4, _5, etc., following the same pattern.

If only one set is defined (API_TOKEN, ZONE_ID, RECORD_NAME), the script will run in single-record mode for backward compatibility, and PROXIED can be optionally specified (default is true).

Example .env file:

API_TOKEN_1=your_first_api_token
ZONE_ID_1=your_first_zone_id
RECORD_NAME_1=sub1.yourdomain.com
PROXIED_1=true

API_TOKEN_2=your_second_api_token
ZONE_ID_2=your_second_zone_id
RECORD_NAME_2=sub2.otherdomain.net
PROXIED_2=false

---

🚀 Usage

Run the script manually or via cron/systemd:

python cloudflare_updater.py

The script will:

1. Get your current public IP
2. Compare it with the last known IP
3. If changed, update all DNS records defined in your environment
4. Repeat every 2 minutes ⏱️

---

📄 Logging

📝 All actions are logged to:

• cloudflare_update.log (file)
• Console (real-time output)

Each record and account is logged separately for clarity.

---

💡 Example Use Case

You host several services at home:

• home.example.com → Your NAS
• cam.example.net → Your security camera
• vpn.mydomain.org → Your VPN endpoint

When your IP changes, all three stay perfectly in sync.

---

🔒 Security

• API tokens should have minimum required permissions (edit DNS in the target zone only).
• Never share your token — use .env files or secret managers.
