Explain the routing between ipv6 and ipv4?

Faced with ipv6 and not understand a bit. Is there any global provider routing from ipv6 to ipv4?
Let me explain.
Configured on 2 debian address. ipv4 traffic goes through your address, ipv6 - using your. Everything is fine.
Now I want to disable 4 version to all requests went through 6.
Now, if the domain name is not displayed in the ipv6 address, then access it there.
How to set up?

No way. These are two parallel worlds.
ipv6 only is far premature
For example, it is very necessary. What to do? To purchase a VDS, it can configure both protocols and roditi from 6 to 4? - paul_Harb commented on July 2nd 19 at 13:30
to roditi from v6 to v4 is not. - Reb commented on July 2nd 19 at 13:33

Not every ISP has implemented IPv6 in its network, for the most part it has to do with outdated equipment, if home or office replacement router is the issue 40-50$ then wire your core to replace it will be much more expensive and exhaust will not happen (although I know the dash which ip6 sells as a service).

In fact, within the network can use any standard but in the world, you still get the ip4.
As said above "only ipv6 is far premature,"

"I want to turn off version 4 so that all requests went through 6"
The idea is you need to:
1) Remove A record from DNS, leaving only the AAAA record in DNS
2) Web server should listen on ipv6 address or "all addresses".
3) Means that the server itself is already configured for ipv6, and ping ipv6 address.
If something is not working - need to see patient - it may be the case in iptables, or you have problems accessing via https or just need to wait for DNS updates.

In the local network can enable IPv6 if it supports all your hardware.
The Internet is a little trickier, depends on the provider. But there is another tunnel brokers and mechanism 6to4
