Then you are not looking very far, or more likely, you are not a network
technical person and therefore feel no need to keep up to date on the
details of the technology. For at least ten years now we have had
interworking mechanisms that allow IPv6 networks to access the IPv4
Internet and vice versa. New ones are coming along all the time such as
6VPE. There are no magic bullets, but there are many ways of making
interworking function well enough to keep a network operator growing and

Why don't you do some of your own research. This information is not that
hard to find and pointers to much of it are on ARIN's IPv6 wiki at

If you don't even know the fundamentals, then why are you in this
