What is an advantage of using IPv6 over IPv4?

The advantage of using IPv6 over IPv4 that stands out is the provision of a much larger address space. IPv4 is limited to 32-bit addresses, which allows for approximately 4.3 billion unique IP addresses. However, due to the rapid growth of the internet and the increasing number of devices connected to it, this address space has proven insufficient.

IPv6, on the other hand, utilizes 128-bit addresses, which vastly expands the number of potential unique IP addresses to about 340 undecillion (3.4 x 10^38). This immense address space ensures that every device on the planet can have its own unique IP address, facilitating the seamless connectivity required in today’s increasingly interconnected world.

Having this larger address space not only helps accommodate the growth of devices but also simplifies network management and reduces the need for practices like Network Address Translation (NAT), promoting end-to-end communication.
