There is no need to disable ipv4 to use ipv6.
1. Describe the main features that differentiate IPv6 from IPv4
I guess NAT64
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.
uLol(^^,)!
IPV6 is less vulnerable to DNS Spoofing IPv4 addresses use 32 bit or 4 bytes for addressing IPv6 addresses use eight bit segments.
There are a number of technologies that can provide IPv6 translation for IPv4 users, most commonly Dual Stack and 6 to 4 tunneling. DUAL STACK involves running both IPv4 and IPv6 on a single router with the router managing the implementation of either protocol as and when necessary. 6 to 4 tunneling encapsulates an IPv6 frame in and IPv4 frame for tansport over an IPv4 network either to its destination address or a network where the IPv4 frame can be discarded.
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.
