The handling of multiple IPv6 addresses is a regular aspect of IPv6 implementations. IPv6 was designed to accommodate a vast number of unique addresses, allowing each interface on a device to be assigned multiple addresses without the limitations often found in IPv4.

In IPv6, it is common for devices to hold more than one address for various purposes. These can include global unicast addresses, link-local addresses, and unique local addresses, among others. This multi-addressing capability is considered standard practice and is integral to the operational flexibility and routing efficiency provided by IPv6. Moreover, it facilitates functions such as network renumbering, addressing policies, and load balancing.

The other choices suggest alternative methods for handling addressing, which are not needed in the context of IPv6. Secondary addresses imply a strategy used predominantly in IPv4 to work around address scarcity. NAT, or Network Address Translation, is commonly associated with IPv4 as a technique to extend the limited address space but is generally not implemented in IPv6 due to its vast address availability. Multi-homing involves connecting a single network to multiple providers for redundancy or load balancing but does not directly relate to the handling of multiple addresses on a single device.
