Oooh is that why ipv6 adoption is so regional ( Based on https://www.google.com/intl/en/ipv6/statistics.html ) . Like france ,germany or india having more than 70 % while italy or poland hanging below 20% ? Also judging from this site it seems like ipv6 is actually getting adopted at quite the rapid pace. Even if some regions are faring way worse than the others.
