No-IP is a Free Dynamic DNS and Managed DNS Provider, that we can use to get a free domain name. There a lot of free Dynamic DNS services, you can find a good comprehensive of them here that we can choose from, but this was the first service that I personally tried.

The good with this service is that we have a big selection of free domain names that we can choose, so we can easily find a domain that is available for the hostname we want to have.

The negative is that every 30 days they send a notification email, and we have to sign in to and confirm that we still use the hostname. After some time that I have used the service, I can say that it becomes annoying to verify it once every month.

Install & Configure noip2

Login as root

sudo su

Type the following commands:

cd /usr/local/src/
tar xf noip-duc-linux.tar.gz
cd noip-2.1.9-1/
make install

On the configuration stage:

  • Add email and password.
  • The hostname to update (choose only one).

To launch the client


NOTE: You have to stop it to make it a service later.

Add an executable (noip2) as a service

Create noip2.service in /etc/systemd/system

And add the following:

Description=No-Ip Dynamic DNS Update Service



Restart systemctl to accept changes

sudo systemctl daemon-reload

Enable service

sudo systemctl enable noip2

Start service

sudo systemctl start noip2

Restart service

With a restart, it updates the public IP:

sudo systemctl restart noip2

See logs

sudo journalctl -u noip2
