wget --content-disposition https://www.noip.com/download/linux/latest
tar xf noip-duc_3.3.0.tar.gz
cd /home/$USER/noip-duc_3.3.0/binaries && sudo apt install ./noip-duc_3.3.0_amd64.deb
Once installed, run noip-duc to start the program.
You will want to explore the various options, so run noip-duc --help to see the available commands.

For Windows:

Our Dynamic Update Client runs on your computer and checks frequently for an IP address change. When a different IP address is detected, the DUC automatically updates your hostname to the correct IP address.

Download the DUC
Open DUCSetup_v4_1_1.exe and install the DUC.
Enter the username/email and password you received when creating your DDNS Key. If you have not yet received a DDNS Key, first create a hostname or a group.
Select the hostname(s) or group(s) you would like to update.
