Also, France and Germany are around 50%...
Mobile is king in India. Low levels of Infra.
Korea (and China) dispute the measurement: they both say the external parties (Google, Akamai, APNIC (where i work) and others) mis-measure. I think the mis-measures agree so much, it can't be a mistake.

What do you mean?
Edit: That they all independently measure and reach the same 14%?
It might be that Korea invested a lot, early on, to have great Internet coverage and speed (which is the case), but now they have a lot of hardware that is incomptable with IPv6. And it isn't worth it to replace all that just for that feature.
Germany is dominated by DT (Deutsche Telekom) and what they do, moves the market. the UK is all about Sky (was News ltd, now Comcast, who are also behind a lot of the US domestic IPv6). Sky do remote management of the CPE and were able to upgrade their entire customer base (mostly) with remote upgrade version-by-version. Really high penetration. This caused Virgin and BT to have to think about how to compete for mindshare.
