Final answer:
True, an interface can have multiple IPv6 addresses. This allows for different types of communication and enhances privacy and connectivity. The IPv6 architecture is designed to support complex networking configurations seamlessly.
Step-by-step explanation:
True, you can have multiple IPv6 addresses assigned to one interface. In IPv6, it is quite common for an interface to have several IPv6 addresses. This is enabled by the IPv6 architecture, which allows multiple addresses of different types to coexist on a single interface. For example, a network interface might have a globally unique address (GUA) for communication across the internet, a link-local address for local subnet traffic, and unique local addresses (ULAs) for local communications not meant to be routed outside of a site. Interfaces may also have multiple GUAs if they are connecting to different public networks, enhancing both privacy and connectivity.
This capability is part of what makes IPv6 so adaptable and powerful compared to its predecessor, IPv4, which typically assigns one IP address per interface unless using aliases or sub-interfaces. The inclusion of multiple addresses per interface in IPv6 is designed to aid in auto-configuration, ease of management, and the support of more complex network arrangements seamlessly, promoting better network organization and security practices.
