What type of address does IPv6 primarily aim to provide?

IPv6 primarily aims to provide unique addresses. This is crucial for the expansion of the internet, as the traditional IPv4 system faced a limitation in the number of available addresses due to the rapid growth of devices connected to the internet. IPv6 introduces a vastly larger address space, allowing for the assignment of unique addresses to a virtually limitless number of devices. This uniqueness is vital to ensure that each device can be individually identified on the network, facilitating communication and data transfer without confusion or conflict.

While private addresses serve specific needs within local networks, the focus of IPv6 is on enabling unique addresses that can be used at a global scale. Public addresses also exist in IPv6, but the emphasis on unique addressing goes beyond just public visibility; it relates to the overall architecture of the internet and the need for every device to have a distinct identifier. Shared addresses can lead to conflicts and are not ideal in a system that requires precise routing and identification of individual devices. Hence, uniqueness is the primary characteristic that IPv6 aims to secure.
