Detailed explanation-1: -is necessary when the sender wants to use IPv6, but the receiver does not understand IPv6. Explanation: Header translation is used when the sender wants to use IPv6, but the receiver does not understand IPv6.

Detailed explanation-2: -The IPv6 flow label is considered during header translation. Both NAT64 and DNS64 are required for IPv6 if either is used. Which of the following is not an IPv4/IPv6 transition strategy? The dual-stack approach refers to a network node having both IPv4 and IPv6 support.

Detailed explanation-3: -NAT Protocol Translation When the IPv4 host sends a request packet to the IPv6 server, the NAT-PT device/router strips down the IPv4 packet, removes IPv4 header, and adds IPv6 header and passes it through the Internet. When a response from the IPv6 server comes for the IPv4 host, the router does vice versa.

Detailed explanation-4: -Explanation: There is no concept of broadcast address in IPv6. Instead, there is an anycast address in IPv6 which allows sending messages to a group of devices but not all devices in a network. Anycast address is not standardized in IPv4.
