I normally agree with you, Seb :-) but I disagree here. No greenfield project in 2012 should not be dual stack, because IPv6 is not an experiment any more. It is production safe in hosting environments. Further, it is extremely likely that the Olympic Games will be staged *after* the RIPE region v4 runout (and the APNIC v4 runout was long ago), so there is an increasing risk that users will be visiting services relating to the Olympics through CGNs - debugging performance issues relating to overloaded or broken CGNs is going to be pointless, but debugging reachability issues related to IPv6 solves the problem for ever. Users don't need to know what IPv6 is, if we do our job properly. The challenge (largely solved) is for all this to 'just work', as you comment. CGN and v4 life extension makes that harder, end-to-end and dual stack makes that easier. Andy Davidson
