Cirrect me if I am wrong, least 4 bytes of IPv6 address is IPv4 address which can be used for IPv4 routing. So ideally there should not be any problem. (not sure if there is any x2 angle to this)

Best answer

IPv4 and IPv6 cannot talk to each other without having a translator between them as these are two different protocol stacks. The IPv4 packet can contain destination IP address which can be IPv4 only. Same is applied for IPv6 as well.
But if a translator device like NAT64 is present in the middle, X2 link is possible.
