I think of myself as technically inclined. I have installed Linux multiple times and have basic command line knowledge, and I’ve programmed in many languages, with the most experience making a static website game using HTML/CSS/JS.
Additionally, I own the superspruce.org domain (my registrar is Dynadot), but I don’t really know how to wield the power of owning a domain. I also have some spare computers to be used for hosting, a 2009 laptop running Lubuntu and a 3900X+32GB RAM desktop other running KDE Neon, but I’m also open to experimenting with cloud hosting too (I know, sacrilege here).
However, I don’t know much about the TCP/IP protocol or other networking protocols. I’m happy to learn, but the curve would need to start gently.
I would want to try hosting my websites, and also a personal non-federated Lemmy instance to serve as a archivable forum for my games. Even if it’s not very useful, it’s great experience.

Here’s some links to some online courses to get you started. I think you might have to pay for the second one, but the first one, from Cisco, is free. (You’ll need to create a Cisco account, however.)
It’s absolutely great experience, and I could write a whole screed about what to look up, or I could point you to sources that are better organized than me, so I’m going with the latter.
