My data on customers supposed to be 100% dual-stack (unless they
explicitely disable IPv6 on their side, which some of them do) says 25%
on best days. It used to be up to 35% in late 2015.
For reason unknown, it was going slightly down during 2016, with a
sudden extra decrease in january this year.
