route redirection and protocol unreachable
ARP ICMP IRDP
Assuming IPv4 ICMP. Ping uses IP for transport. Ping in itself is an "Echo Request", which is a function of the ICMP protocol. The IP Packet will carry the ICMP protocol from end-to-end. ICMP has a protocol number of 1, so the "Protocol" field in the IPv4 header will contain "1" as a reference to the ICMP payload. For IPv6, ICMPv6 is used, and the transport will be IPv6.

Off the top of my head it is IPv4 IPv6 Appletalk IPX
Tunneling in the context of migrating from IPv4 to IPv6 refers to the technique of encapsulating IPv6 packets within IPv4 packets to facilitate communication between IPv6 networks over existing IPv4 infrastructure. This allows organizations to gradually transition to IPv6 without needing to replace all their IPv4 equipment immediately. Tunneling can be implemented using various protocols, such as 6to4 or Teredo, enabling interoperability between the two IP versions during the transition period.
There is no need to disable ipv4 to use ipv6.
1. Describe the main features that differentiate IPv6 from IPv4
I guess NAT64
NAT64 serves as a mechanism to facilitate communication between IPv6-only and IPv4-only networks by allowing IPv6 clients to access IPv4 services. It translates IPv6 packets to IPv4 packets and vice versa, enabling seamless connectivity without requiring the IPv4 service to be directly accessible via IPv6. This is particularly useful during the transition period from IPv4 to IPv6, ensuring compatibility and interoperability across different network environments.
IPv4 and IPv6 are two different protocols . The two protocols are not compatible with each other. But they can exist in a same network together.No, those are two different protocols. However, they can co-exist in the same network (this is known as "dual stack").No, those are two different protocols.

In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.
While IPv6 is based on IPv4, it is superior. The main characteristic that shows its enhancement over IPv4 is that it processes faster.
