IPv6 Measurements
This page contains an index of reports generated by the IPv6 capability test script. A description of the script itself and the statistics gathered by the script in April 2010 can be found in the article "Measuring More IPv6" (http://www.potaroo.net/ispcol/2010-04/ipv6-measure.html.
An associated report contains data that examines the connection failure rate recorded as part of this measurement activity.
