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.
Go for a book to gain the knowledge, examples: https://bookauthority.org/books/best-network-protocols-books
Check Gentoomen Library and anarcho-copy, both have a huge curated list of books on everything, including networking.
The reality is that you won’t learn much just by reading, you need to try to debug stuff and eventually work in the area to truly learn.
But I am sure there are plenty of tutorials and video courses in various platforms where you can learn a bit on the topic. Coursera might be a good place to start as you can enroll for free to those courses if I am not wrong.
I’m also a person that has always struggled to learn by solely reading. Typically a combination of video tutorials and documentation, while actually doing the work on my end, is how I usually grasp concepts.
Imagine trying to learn math without solving any problems along the way.
You can use emulation to practise. Gns3 or packet tracer are example of visualising networking hardware to play out different ideas. Jeremy’s it lab has plenty of cisco related videos to teach you.
This way you can fuck around without the wife getting angry she lost instagram access again and again and again.
Computer Networking: Top down approach book is awesome honestly

Do you like dry reading? I do, and I started here http://intronetworks.cs.luc.edu/
Michael W. Lucas’s “Networking for System Administrators” is a great resource: https://mwl.io/nonfiction/networking#n4sa
Raspberry Pi + PiHole + PiVPN = Network Gateway Drug
Although, PiVPN is winding down so you might want to find something different instead. Setting up a regular Wireguard VPN isn’t so bad, but it may be simpler to setup a Tailscale Tailnet.
There is always the Network + book. I went through it in 2005, so no idea what the content is like nowadays though
