The clients themselves wouldn’t seem to have much possibility even of using some of the tunneling or encapsulation methods, if they could only talk one or the other.

Actually, I haven’t run across anything that only has IPv6 without also allowing IPv4. But my experience is narrow for this area.

IPv6 interfaces that I’ve directly worked with have handled IPv4-mapped IPv6 addresses, so I haven’t had to dig into it deeply yet.

The rest of the above Wiki link has lots of useful background information that might be helpful.
