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 need to disable ipv4 to use ipv6.
1. Describe the main features that differentiate IPv6 from IPv4
When tunneling IPv6 over IPv4, the overhead primarily consists of the additional IPv4 header and any encapsulation overhead. An IPv4 header is typically 20 bytes, while an IPv6 header is 40 bytes. Thus, the total overhead for tunneling one IPv6 packet over IPv4 would be 20 bytes, resulting in a total packet size increase of 20 bytes for every IPv6 packet transmitted. This additional overhead may impact performance, especially in networks with high traffic or limited bandwidth.
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.
I guess NAT64
tunneling
In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.
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.
