And that is that !

Since there are no features that cannot be had with IPv4 this only
happens when cost of deployment of IPv6 for a given network (part) is
less than that of doing the same thing with IPv4.  Since the only real
feature of IPv6 is more addresses this only happens if it is too
expensive to obtain the IPv4 address space that is required by the
deployment.  *)

So far this has not happened often, but it already has happened in the
judgement of some, like Comcast, and they deployed IPv6. 

It will happen more frequently and those who are not anticipating and
planning ahead will pay the price for that.  And they will complain that
they have not been warned .....  But that is life. 


*) Note that features required by some deployments require more address
space that can be easily obtained in IPv4.  Currently these are rare but
they exist.
