I love Pop OS because it got me back into Linux after ditching it for windows for the last 10 years, partly to do .net development and partly because I hated the state of Ubuntu/Unity.
As soon as cosmic is stable and easy to install on Nix I’ll switch to it.
Domains need to be registered annually and DNS servers are needed to route traffic to them. But using an IP directly, you don’t need to worry about domain registration issues that can brick your systems, and you don’t have to worry about DNS providers knowing about your traffic (or maintaining your own private dns).
If it’s not a user trying in a memorable domain, an IP serves much better.
Context clues my dude. You said it yourself, Linux runs the majority of servers, so what would be “the recent rise of Linux” talking about? Linux for end user clients (desktop).
