What are the different types of addresses used in IPv6 referred to as?

In the context of IPv6, the different types of addresses are collectively referred to as address types. This terminology is widely accepted within networking literature and documentation. IPv6 addresses can be categorized into various types such as unicast, multicast, and anycast, each serving specific purposes in the network.

Using the term 'address types' accurately conveys the diversity of address formats and their intended functions in the IPv6 architecture. Other options like "IP categories," "address classifications," or "network identifiers" do not specifically capture the established terminology used within the context of IPv6 addressing. While they may relate to networking concepts, they do not reflect the standard nomenclature that experts and practitioners utilize to discuss the different addresses in the IPv6 protocol.
