Dynamic DNS client that automatically updates IP address for my server?

Hi I wanted to get a dynamic DNS and I wanted to download a client into my server (running Opensuse 15.1) that automatically updates the dynamic IP address so I dont have to manually go in and change it all the time.

How can I do this?
I saw on dyndns.com they use oracle… Should I call Oracle or is there a smaller company I can go with?

Whatever new software you want to add to your system, I should first upgrade to 15.2 to have a supported version of openSUSE. More chance that software will be available.
