What are the benefits of IPv6 towards IPv4?
The benefit of IPv6 is its huge address space. While IPv4 has 32-bit address space that can identify only 4.3 billion (4294967296) nodes at maximum, IPv6 can identify 340282366920938463463374607431768211456 nodes with its 128-bit address space. This means IPv6 addresses can be assigned to almost anything connected to the Internet. In the future, more and more devices will connect to the Internet and they will communicate with each other directly. In such situation, the mechanism to identify each device with global accessible identifiers becomes more important. IPv6 is one of the realistic solution for the future networking environment.
