The interesting aspect here is that if you wanted to deploy a new IPv6-only access network (which might be of interest in some parts of the world) then you'd only need to translate about half your traffic. The rest can flow natively. I would have guessed that that figure would be much higher. >> It would be interesting to hear your view on what those are and whether >> any are not being addressed.

I would be much more concerned with protocol gaps (aside from the 'religious' discussions over topics via DHCPv6 vs RA, etc!). >> In terms of content delivery, clearly Google and Facebook don't see >> issues (though any access issues lead to calls to ISPs not to them :) > > Indeed, and both google and Facebook run their own home build software, > most people don't. I believe Google do now, based on a discussion earlier this week with one of their staff, but I recall for the previous IPv6-day stuff they used Akamai, e.g. for YouTube content, which they left available that way after June 2011? >> That at least is excellent news!
