1. Describe the main features that differentiate IPv6 from IPv4
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
There is no need to disable ipv4 to use ipv6.
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.
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.
IP is the internet protocol that uniquely identifies a system on a network and there is no difference between IP and IPv4 infact IPv4 is a version of like IPv6.

IP is the internet protocol that uniquely identifies a system on a network and there is no difference between IP and IPv4 infact IPv4 is a version of like IPv6.
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.
There is no direct conversion.
