Not possible for them to fully disable the ipv4 network. I dont think they will implement the 6to4 tunnel or NAT,as currently does not needed for the usage.
The world never want to shutdown the ipv4 network,it is just because the ipv4 pool is not enough for device or server.
And i think the reason they want to move all user to private ip is because most user does not have the need for public ip, except for cctv,private game server,nas,torrenting,Game P2P connection,or something else.
For home web hosting,i think it is not a proper usage for home user,so i dont included on the needs.
And also if all change to IPv6 which mean in normal situation all device is public online without firewall,actually it is more easily to attack then having ipv4 with nat / firewall.
(In my memory currently most home router does not have the IPv6 firewall implementation? or currently not enough secure for ipv6?)
First, there is nothing to scare from being on a public IP allocation, as long as your router security are configured right. One of the most common myth regarding IPv6 security is that the lack of NAT makes IPv6 less secure.
NAT is often seen as a security feature in IPv4 networks, but the reality is NAT does not provide any real network security.
Although IPv6 is an global address, but it does not mean you can get there from wherever you are on the public internet. This is what firewalls were designed to do.
A stateful firewall uses state to determine which packets to allow into the network. That is, it remembers when you send packets out and to whom so that it can allow packets back in only from those hosts with which you initiated communication. In other words, a stateful firewall stops all incoming traffic unless it is a reply to valid traffic that you sent.
While the NAT may provide a bit of obfuscation, by hiding your internal addresses, it is really this stateful firewall function that protects your network from unwanted intrusion.
