How to access ipv6 host via ipv4?

Question

Computer networks

From all the tone of the material, I did not clearly see hints that it is possible to connect to an IPv6 machine from a remote IPv4 machine, but I did not see a direct instruction anywhere. Knowing that technologists are different, I do not believe in such a possibility. But my heart feels the opposite.
So given. A host with a gray IP behind the provider's nat, it is also a gateway and a router and a proxy and nat. By miredo I get a permanent ipv6. Well, then I want to get access from anywhere and from gray ipv4 and white ipv4 to this gateway, on all ports, in order to satisfy any of my needs.

Answer 1

The heart does not deceive you, tie IPv6 and IPv4 together, perhaps read the CCNA introductory course
