And at what percentage of deployment of IPv6 will we see people decide
that they no longer need to support IPv4 access
to their web site? (Oh, sorry you were talking about SNI. My bad. :-)
Personally, I think it is basically the same question and should have
similar answers. Some people seemed to think that the number is
100%. From what I can tell about SNI, WIndows XP clients not using
Firefox or Opera are never going to get it. I think Windows XP is
down to just over 50% which is way more then IPv6 deployment numbers
at this point. We may find that the same people who don't have IPv6
will also be running Windows XP and Internet Explorer. So the choice
will be to either switch to SNI or switch to IPv6 and lose access to
the same customers in either case.
