Hi,

> Who writes some sentence, surely knows that today IPv6 addressing in Italy is used only by Facebook, Google, Youtube and some other else, but most of sites are only reachable by IPv4.
> So, please, let me know how to migrate all our customers to IPv6 giving them access to the whole internet, as today, and we’ll make it.

It's off-topic on this list, but just to give you a sample of the solutions you might deploy:

Stateful NAT64: Network Address and Protocol Translation from IPv6 Clients to IPv4 Servers
https://tools.ietf.org/html/rfc6146

464XLAT: Combination of Stateful and Stateless Translation
https://tools.ietf.org/html/rfc6877

Dual-Stack Lite Broadband Deployments Following IPv4 Exhaustion
https://tools.ietf.org/html/rfc6333

Mapping of Address and Port with Encapsulation (MAP-E)
https://tools.ietf.org/html/rfc7597

Mapping of Address and Port using Translation (MAP-T)
https://tools.ietf.org/html/rfc7599

An Incremental Carrier-Grade NAT (CGN) for IPv6 Transition
https://tools.ietf.org/html/rfc6264


As you can see you are not the only one who needs to run a network with a shortage of IPv4 addresses, and solutions have been designed. There are some well-known examples that use these technologies. T-Mobile runs NAT64+464XLAT, UPC runs DS-Lite etc. Implementations are available on the market. Running an ISP on just IPv4 isn't possible anymore (basic math) so you'll have to learn to deal with that, just like everybody else. This mailing list is not the place to argue that point.

It is clear that you need *some* IPv4 to be able to talk to others that only talk IPv4, which is why we have the final-/8 policy. Being able to run/expand a network (especially ISP networks) completely on public IPv4 without NAT and/or IPv6 has ended years ago, and no policy change is ever going to be able to change that.

People that are still in denial and want to discuss how to run their networks on IPv4-only without having anything to do with IPv6 should start an IPv4 working group...

Cheers,
