What is a primary benefit of using IPv6 over IPv4?

The primary benefit of using IPv6 over IPv4 is that IPv6 offers a significantly larger address space. IPv4 is limited to approximately 4.3 billion unique addresses, which has become insufficient due to the tremendous growth of internet-connected devices. IPv6, on the other hand, utilizes a 128-bit address scheme, allowing for approximately 340 undecillion (3.4 x 10^38) unique addresses. This vast address space addresses the exhaustion of IPv4 addresses and facilitates the expansion of the internet, enabling every device to have its own unique address without the need for complex workarounds like Network Address Translation (NAT). The transition to IPv6 ensures that future devices can continue to connect without the limitations imposed by the IPv4 addressing system.
