Detailed explanation-1: -Although both IPv4 and IPv6 provide IP addresses, they can’t communicate with each other. However, both can co-exists in a network. This is known as a dual-stack. Tunneling is another approach in which a tunnel is created within an IPv4 region that allows encapsulated IPv6 packets are sent.
Detailed explanation-2: -IPv6 vs IPv4 Because direct communication between IPv4 and IPv6 is not possible, all three elements of the connectivity ecosystem must be aligned on the same standard: content, devices, and networks.
Detailed explanation-3: -IPv4 and IPv6 are two completely separate protocols, with separate, incompatible packet headers and addressing, and an IPv4-only host cannot directly communicate with an IPv6-only host. The correct way to do this is to dual-stack one or both hosts so that they run both the IPv4 and IPv6 protocols.
