Will ipv4 clients have access to my server if the server has ipv6?

Question

Computer networks

Good day to all. There is a powerful server, but only one white ipv4 address is connected to it, the idea is to set up virtual machines with white ipv6 on it. Here, in fact, the question is, if a site is installed on one of these machines, will clients with only an ipv4 address have access to it? And how can I check the connection to such a virtual server, for example, log in via ssh, if I have ipv4 myself?
Thank you.

Answer 1

In the pure case, no. Maybe 6to4 will help you .

Answer 2

There is a powerful server, but only one white ipv4 address is connected to it, the idea is to set up virtual machines with white ipv6 on it.

If you need to run several servers and organize access to each, then it’s easier, in my opinion, to buy IPv4 addresses (if the hoster provides such a service) and set up bridging (better) or NAT (more crutch) for virtual servers.
If you still want to experiment with IPv6, then

Here, in fact, the question is, if a site is installed on one of these machines, will clients with only an ipv4 address have access to it?

I think no. In order for IPv4 clients to access your IPv6 server, they (clients) will need to use some IPv6-over-IPv4 solution, such as Teredo (unlike 6to4, Teredo encapsulates data in UDP datagrams, thereby simplifying interaction with NAT , which the client is likely to have).

And how can I check the connection to such a virtual server, for example, log in via ssh, if I have ipv4 myself?

Just like a potential client. Raise the appropriate interface (teredo), establish an SSH connection, specifying the IPv6 address of the server.
In this comment, I assumed that your hoster has IPv6 connectivity (i.e. it announces its IPv6 prefixes to the Internet). If the assumption is wrong, then the server will have to use some kind of IPv6-over-IPv4 solution.
