@tute123456 If you have the noip2 binary then you are running the old 2.x client. In the new 3.x client the binary is called noip-duc. Try which noip2 and which noip-duc to determine which one exists.

If you're on an apt-based system like Debian or Ubuntu you can find the version with dpkg -l 'noip*'. On Fedora and possibly other rpm-based distributions the command may be like dnf list installed | grep -i noip. I don't have a rpm-based system handy to verify.

Thank you, you could pass me a link for the installation of version 3.3, or if possible a guide to erase the old 2.x and install the new one, thank you very much!
