Need of IPv6
As we are nearly out of the four billion addresses available in IPv4, IPv6 could be the solution to many problems.
IPv6 addresses are four times the size of IPv4 addresses.
An IPv4 address has 32 bits, while IPv6 address has 128 bits.
For IPv4, this pool is 32-bits (232) in size and contains 4,294,967,296 IPv4 addresses.
The IPv6 address space is 128-bits (2128) in size, containing 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses.
