Kabel Deutschland, T-Mobile USA, and Facebook are examples of companies
who have already or are in the process of moving their network
infrastructure to IPv6-only. Without going bust.
What you *do* need, is some form of connectivity to the IPv4 internet.
But there are smarter ways to do that than dual stack. Seriously, if
you're building a network today, consider making IPv4 a legacy "app" or
service running on top of an otherwise IPv6-only infrastructure. Five
years down the road you'll thank me for the tip. :-)
