Re: Nope, never saw this coming
"This typically means that your laptop or phone behind your home router gets a different IP every day, the first part of the address stays the same, the second part varies. How big the size of the static part is compared to the variable part varies per ISP. If they give you a measly /64 a different section will change than if they give you a /56 or a /48."
Given the HUGE size of IPv6 don't you think it is trivial to just bin addresses in such sized blocks? After all it is only YOU who is populating the allocated block. Yes, it might be harder to track people in your home individually (just as for IPv4 NAT) but your home use is simple to track and not per-home swapping to worry about.
