Once you get some experience with the conveniences and other advantages it brings, it’s actually pretty easy to wrap your head around.
I agree with Owen (and the others who have chimed in) on that one. As long as you're thinking and talking about individual addresses you're stuck in an IPv4 mindset. One of the points in having 64 bits reserved for the host portion of the address is that you never need to think or worry about individual addresses. IPv6 eliminates the address scarcity issue. There's no reason to ever think about how many individual addresses are available on any network. The answer is always more than enough. Instead you think about networks and network size. Also, good luck trying to shove the IPv6 genie back into the bottle. I doubt you're going to have much success. I know my large organization has seen the percentage of email traffic on our edge MTAs using IPv6 steadily grow since we dual-stacked them back in 2012. It's been a while since I checked with the organization responsible for them, but I believe it's somewhere north of 10% of all email traffic now. (I know our heavily used website has reached roughly 20% IPv6 traffic now.) So it's best to just keep working on ways to manage spam in an IPv6 world since that's the present reality. Scott
