As a service provider, I have no choices. I support IPv6, but I don't
decide what applications my customers use or who they will talk to.

http://tools.ietf.org/html/rfc6052 Useful for NAT64 and using the well
known prefix allows for literal IPv4 addressing within an IPv6 only
network where DNS is not used by the application.

I don't disagree, yet there are many applications that still are not
supporting IPv6. I'd presume they will have no choice to stay in
business, but that isn't my concern. My concern as a provider is to give
access to other networks via IPv6 protocol and give access to other
networks via IPv4 protocol.
