If Unicast is one-to-one, Anycast is one-to-many. Anycast is taking the same IP address and assigning it to multiple locations across the network. In the same scenario as above, your website isn’t just hosted at one location (or on one nameserver), it is hosted on multiple name servers, in multiple locations. So, if one server in the Anycast cluster goes down, your website won’t go down with it. The queries will just be answered by the next server instead. Anycast is used to help distribute traffic and query load across the entire network, so one point of presence (PoP) isn’t always doing all of the work. This helps keep the network fast and reliable. Anycast also helps to ensure that someone visiting your website from Tokyo, Japan, queries the server that is closest to their location. This helps to ensure that the website loads quickly.
