I beg to differ. Whilst short term objectives are integration and coexistence, the long term objectives are to get rid of IPv4 altogether. Coexistence introduces some weakness in the stability of the Internet, so the sooner we start the next phase, the better.<br>
</blockquote><div>Aye ...however we want to word it, the ultimate (long term) objective is to get rid of IPv4. It might take a long time (till the relevant applications become IPv6 capable) but once that happens, running dual stack will not only not make sense but also be expensive. That interplay of words might be required to reassure naysayers and the conservative, but let there be no illusions as to what the ultimate objective is, and more importantly people shouldn't be led to believe that coexistence/integration is the end ... it is not, those are only means to and end ... v4 out v6 in.</div>

IMHO, once IPv6 is in wide use, IPv4 will wither away quite naturally, a bit like horsedrawn carriages did when the carriage with a mounted explosion engine became widespread.<br>
