IPv6 report at tronche.com for April 2011 is out.

A little of a surprise, at least for me, is that, although China consistently shows up in the various top 10 of the report, and APNIC has been out of IPv4 addresses this month, RIPE seems actually to be leading adoption, be it by hit number, number of distinct addresses or number of distinct networks seen. This is quite clear on this graphics.

Although adoption is very slow, I take as a good sign that, for the first time, the number of distinct IPv6 networks seen was above 100 for two months in a row.
