install the ddclient to update dynamic DNS

sudo apt-get install ddclient libjson-any-perl libdata-validate-ip-perl

wget https://files.pimylifeup.com/portforwarding/ddclient-3.9.0.tar.gz tar -zxvf ddclient-3.9.0.tar.gz

sudo cp -f ddclient-3.9.0/ddclient /usr/sbin/ddclient

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

NO-IP offers free subdomains

CloudFlare you need to own a domain name

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
