I want to try out some things with a secondary domain. I’d prefer ethical and non-shady providers. I have a fixed IP and a VPS to go with it, so it’s really only about the domain. A subdomain of my current domain is not enough. A subdomain of the provider would be OK but not ideal.
Even paying very little is not an option right now - maybe later.

Doing some preliminary research, the keyword seems to be Dynamic DNS even if I have a static IP. There are providers but those that pop up easily do not instil much confidence.

I want to hear the Fediverse's opinions! I haven't found any recent posts about this.

TIA
