I absolutely hate how dependent we've gotten to IPv4. To the point that Amazon is charging almost $4 a month per IP. It used to be free. These assholes are buying IPv4 addresses so fast that they are literally driving up the price.

Is there a resource that you can recommend on learning IPv6 based on my knowledge on IPv4? A lot of resources I've seen are way over engineered for my feeble brain.

Like I know what IP addresses are and what port numbers are. I don't understand the difference between how IPv6 addresses are assigned (both locally and generally speaking) and what makes it different from IPv4.

I know it's not DHCP.

Edit: This post provides a link to a great summary for those who know IPv4 but need to learn IPv6.

It absolutely can be DHCP. There’s two main ways to do it: stateless auto configuration, and DHCP. Super briefly, you can assign IP addresses the same way you used to if you want, or you can let devices pick their own.

I’m afraid I can’t recommend a great resource, but I really like the Wikipedia article because it’s very precise in its terminology. I appreciate that with learning a new subject. I’m not even that precise here. For example, I use the term IP forwarding more liberally than what it actually means.
