Answer:
anycast
Step-by-step explanation:
The type of IPv6 address that refers to any unicast address that is assigned to multiple hosts is called Anycast address. An anycast address is an IPv6 address that is assigned to multiple network devices in a way that allows data to be routed to the nearest or best destination device. With anycast addressing, a single IPv6 address is assigned to multiple devices, but only one of them is actively serving traffic at any given time, making it a type of unicast address.
Anycast addressing is commonly used for load balancing and to improve the reliability and performance of network services, such as Domain Name System (DNS) servers, content delivery networks (CDNs), and network time servers.
