Availability of Sites over IPv6
It seems there is an IPv6 deployment metric on which Ireland leads the world! At the most recent RIPE meeting, there was a study of the number of the top 100 most visited web sites (according to Alexa) in each country had support for IPv6 HTTP, SMTP or DNS. The results for Ireland are on page 88 of the PDF, where 9 of our top 100 web sites have IPv6 DNS support - which is the the largest number with DNS support of any country. We do not shine so brightly when it comes to web support or mail support (0 and 1 respectively).
