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

The purpose of the IPv4 over IPv6 dual stack in the TCP/IP Protocol is to ensure compatibility and smooth transition between the older IPv4 and the newer IPv6 protocols. It allows devices and networks to support both IPv4 and IPv6 simultaneously, enabling communication with systems that are still using IPv4 while also being prepared for the future adoption of IPv6. This dual stack approach allows for a gradual migration from IPv4 to IPv6 without disrupting existing IPv4-based services and infrastructure.
