Add the following to below the commented header in the file, also remove anything else in the file. We will add more to the file later on with our guides on using No-IP or Cloudflare.

use=web, web=checkip.dyndns.com/, web-skip='IP Address' ssl=yes

CloudFlare and No-IP is that you need to own a domain name to make use of CloudFlare. No-IP However offers free subdomains, meaning it’s a costless service to use.

Cloudflare also offers more protection such as free SSL, anonymized IP, DDOS protection

protocol=cloudflare

server=api.cloudflare.com/client/v4

login=your_email

password=your_api-key

zone=your_domain.com

anything.your_domain.com

sudo /etc/init.d/ddclient restart

You may need to turn off the Cloudflare proxy
