Explain the purpose of the Internet Protocol version 4 over IPv6 (IPv4 over IPv6) tunneling in the TCP/IP Protocol.

The purpose of IPv4 over IPv6 tunneling in the TCP/IP Protocol is to enable communication between IPv4 and IPv6 networks. As IPv6 is gradually replacing IPv4, there is a need to ensure compatibility and connectivity between the two protocols. IPv4 over IPv6 tunneling allows IPv4 packets to be encapsulated within IPv6 packets, allowing them to traverse IPv6 networks. This enables seamless communication between IPv4 and IPv6 devices, ensuring a smooth transition from IPv4 to IPv6.
