Final answer:
It is true that IPv6 packets can be converted into IPv4 packets and vice versa through mechanisms like NAT64, DS-Lite, 6to4, and 6RD, as part of the interoperability required during the transition from IPv4 to IPv6.
Step-by-step explanation:
The statement that IPv6 packets are converted into IPv4 packets, and vice versa, is True. This conversion process is necessary because the Internet is currently in a transition phase from IPv4 to IPv6. During this time, not every device or network supports IPv6, so mechanisms like tunneling and translation are needed to ensure interoperability between the two protocols.
One of the most common mechanisms for this conversion is called NAT64, which translates IPv6 packets into IPv4 packets to allow IPv6-only devices to communicate with IPv4 networks. There's also DS-Lite (Dual-Stack Lite), which enables ISPs to manage the transition to IPv6. Other translation mechanisms, such as 6to4 and 6RD (IPv6 Rapid Deployment), facilitate communication between IPv4 and IPv6 networks by encapsulating IPv6 packets within IPv4 packets for transport across an IPv4 network.
