In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.

IPV6 is less vulnerable to DNS Spoofing IPv4 addresses use 32 bit or 4 bytes for addressing IPv6 addresses use eight bit segments.

127.0.0.1 is the loopback address in IP.... or in the (slightly modified) words of Dorthy Gale when she returned from Oz "There's no place like 127.0.0.1"
IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.

(Internet Protocol) IPv6 is the next step from IPv4. Currently we are not using IPv6 for our networks but soon it will implemented into our networks normally. IPv6 uses 128 bit spaces for its ip addresses were as IPv4 only uses 32 bit spaces. That means IPv6 can support 2128 addresses. I do not think we will run out of addresses with this version anytime soon.
DNS - it handles both IpV4 and IPv6 addressing.

IP addresses are of two types IPV4 and IPV6 . Depending upon the version the length of IP address differs . IPV4 is 32 bit long and IPV6 is 128 bits long.
There is no need to disable ipv4 to use ipv6.
1. Describe the main features that differentiate IPv6 from IPv4
In theory there are 264 available network allocations in ipV6. It is not known how many are actually in use at this time. For a very clear comparison, in IPv4 there is a total of 4,294,967,296 IP addresses. With IPv6, there is a total of 18,446,744,073,709,551,616 IP addresses in a single /64 allocation.

option 3 dynamic 6to4 tunneling. not 100% but like 80% but you can pray for answer
