I have been exploring the world of home servers/self-hosting for a little over a year now, and feel like I have at a decent understanding of a lot of things that go into this. The one thing I am not remotely comfortable with yet is networking. It’s like a foreign language to me.
What are some good resources or projects that I could work on to help me develop a better understanding of this? Or, what helped you advance your networking knowledge? I have an UnRaid machine and a Raspberry Pi 4 (8gb) at my disposal (for any project recommendations). Current router is ISP provided, so nothing fancy.
Don’t bother with the cert if it’s not your job, but at least look into CCNA Routing and Switching. There are tons of courses available, both in person and online, as well as numerous YouTube videos on the subject.
See if your local library or community college has an adult education center that provides a course. At some point, you will need to learn subnetting, which is just math, but practice makes perfect, and your life is easier if you have it committed to memory.
Proper written work is still one of the most effective ways to do this.
