Mark -- thank you so much for this information.

Knowing that I needed to understand something called "DHCP PD" was the
most valuable thing I've learned about ipv6 in the past decade.

At $WORK we don't use v6 at all. (Fortune 500 company; I can deploy v6
as much as I want on the segments I control, but the larger company
does nothing with it.) So while I know how to set up and use ipv4
pretty well, I knew essentially nothing about v6 other than what I'd
read on my own time.

Not knowing how my home ISP equipment even acquired a v6 address (must
less how it handed them out to my home LAN devices) was very
frustrating, and reading about v6 in general was not very enlightening
for me. So this nugget of info -- "DHCP PD" -- was a godsend. By
looking up information related to it I was able to dramatically
increase my understanding of v6.

So again, thank you!
