Script for servers with dynamic IPs that automatically updates Cloudflare DNS records whenever it changes.

Cloudflare DNS Auto IP Updater

This is a script I made that will automatically update my A record's IP address whenever my web server's IP changes.

I don't have (nor can I afford) a static ip, meaning that my IP address constantly changes. Whenever it does change (usually while I'm sleeping), it means that my site becomes completely inaccessible. So, I attempted to create a solution, which is this script. It can also send you an email and log all IP changes to a file to let you know it's been updated.

Be aware, this only works if your site is on the Cloudflare CDN. See the requirements below:

Requirements:

• Python 3.6 or above
• Python requests library (install using pip3 install requests)
• A Cloudflare account with website
• Cloudflare API Bearer Token
• Need to know your zone ID
• The ID of the A record you want to change

Optional:

• SMTP email, to send an update when the IP changes

Installation:

On your web server, in any directory, clone this repository:

git clone https://github.com/pigeonburger/cloudflare-ip/

Then, open the file cfauth.ini in that folder and replace <YOUR_ZONE_ID> with your actual Cloudflare Zone ID, <YOUR_BEARER_TOKEN> with your API bearer token and <YOUR_DNS_RECORD_ID> with the ID of the DNS record you want to change.

If you want email support, add your SMTP details, otherwise just delete everything at the bottom of the script.

Then, if you've done everything, run the cfautoupdater.py file!
