The writing format of an IPv6 address must take into account the following rules: Four bits (half byte) can be represented with a single hexadecimal value.The base numbering system 16 uses the numbers from 0 to 9 and the letters from A to F.The hexadecimal system is a sixteen base system.IPv6 addresses are 128 bits long and are written as a string of hexadecimal values. An IPv6 package is translated into an IPv4 package and vice versa. Translation : Network address translation 64 (NAT64) allows IPv6-enabled devices to communicate with IPv4-enabled devices using a translation technique similar to NAT for IPv4.The IPv6 package is encapsulated within an IPV4 package. Tunneling : is a method to transport an IPv6 packet in an IPv4 network.The devices execute IPv4 and IPv6 protocol stacks simultaneously. Dual-stack : allows IPv4 and IPv6 to coexist on the same network.Migration techniques can be divided into three categories: The IETF created various protocols and tools to help network administrators migrate networks to IPv6. The transition is expected to take years. In the near future, IPv4 and IPv6 will coexist. There is no single date to transition to IPv6. IPv6 resolves the limitations of IPv4 and includes additional improvements, such as ICMPv6.IPv6 has a larger 128-bit address space, which provides 340 sextillion addresses.IPv4 has a theoretical maximum of 4300 million addresses, plus private addresses in combination with NAT.With a growing Internet population, a limited space of IPv4 addresses, problems with NAT and the Internet of things, it was time to start the transition to IPv6.Projections indicate that the IPv4 addresses of the five RIRs between 20 will end.The depletion of the IPv4 address space was the factor that motivated the migration to IPv6.IPv6 is designed to be the successor of IPv4, but why? We explain briefly: You will have the complete understanding of IPv6 after reading this.
