Why is IPv6 needed in the world today?
IPv4 allows for 232 = 4.3 billion addresses. However, only 3.7 billion are usable because of reservations and classful addressing. The current IPv4 address space is exhausted, and IPv6 allows for 2128 = 3.4 × 1038 addresses. IPv6 still requires NAT for backward compatibility with IPv4. Although IPv4 is slowly being replaced with IPv6, IPv4 is still dominant in networks and the Internet. IPv6 does not need to be subnetted like IPv4 by borrowing bits from the network mask; there are 16 bits dedicated for subnets.
