Which Internet Protocol version 6 (IPv6) transition method involves providing complete support for both IPv6 and Internet Protocol version 4 (IPv4)?

Which Internet Protocol version 6 (IPv6) transition method involves providing complete support for both IPv6 and Internet Protocol version 4 (IPv4)?

• A. Dual Internet Protocol (IP) layer
• B. IPv4 compatible IPv6 addresses
• C. Automatically tunneling of IPv6 over IPv4
• D. Configured tunneling of IPv6 over IPv4

Answer: (A)

The Dual Internet Protocol (IP) layer method is designed to provide complete support for both IPv6 and IPv4, enabling systems that use either protocol to communicate with one another effectively. This method operates concurrently on the same device, allowing it to send and receive packets regardless of whether they are using IPv4 or IPv6. This dual-stack approach is critical as it facilitates a smooth transition as networks upgrade from IPv4, which has limitations in terms of address capacity, to the more advanced and expansive IPv6. By implementing this method, network infrastructure can support applications and services that rely on either protocol, ensuring compatibility and communication across diverse systems during the transition period. This allows organizations to gradually migrate to IPv6 while still maintaining the functionality of their existing IPv4 services, which is essential for preventing disruptions in service.
