Anyone knows of a well-rounded guide that explains the structure of the Internet at large? I know everything listed in the one you linked, but I have a nebulous idea of how anything works after my packet exits my gateway.

So, BGP, autonomous systems, peering agreements and other site-to-site routing protocols that keep the entire Internet infrastructure ticking along.

I don't know of any one resource that gives a overview of everything, I find that browsing Wikipedia for each topic gives a good overview of each topic though, with the overview being the "Internet Architecture" category: https://en.wikipedia.org/wiki/Category:Internet_architecture

Some bookmarks I have regarding BGP and peering that dives into it a bit:

I found Cantrill’s course pretty solid. It is free and you can just skip to DNS & DNSSEC.

Oh, that's exactly what I was looking for. Thanks!

Be suspicious of anything that includes DNSSEC in the "tech fundamentals", since it's rarely implemented (low single digit percentage uptake in the major TLDs). What other complexity are they failing to screen out?

Agreed and yeah he mentions that. I think he mostly just makes you familiar with DNSSEC because he sells AWS certification courses and it will come up on the Networking Specialty. The entire segment is only like 90 minutes so it’s not crazy in depth.

I thought "How the Internet Really Works" (https://nostarch.com/how-internet-really-works) was pretty good.
