Dual-stack in the home networks will stay with us for a long time (beyond 2020!) until v4-only user devices and v4-only apps get refreshed. Of course, this doesn't mean that the ISP access needs to stay dual-stack, thanks to MAP, 464XLAT etc. Cheers, Rajiv Sent from my Phone On Apr 7, 2013, at 3:15 AM, "Fabien Delmotte" <fdelmotte1@mac.com> wrote:
CGN is just a solution to save time, it is not a transition mechanism through IPv6 At the end (IPv6 at home) you will need at list : Dual stack or NAT64/ DNS64
My 2 cents

I wonder how much more painful just upgrading the dsl plant to support v6 would be vs deploying the cgn equipment and funneling users through that :(
IPv6 deployment is not a short term solution to IPv4 address depletion. Would you be less upset if there was IPv6 access and CPE based DS Lite (ie your IPv4 is still CGN:ed, just in a different way)?
CGN is here to stay for IPv4. The solution for long term Internet growth is IPv6.
