what is anycast dns
In Anycast DNS, there is a one-to-many association between network addresses and network endpoints: each destination address identifies a set of receiver endpoints, but only one of them is chosen at any given time to receive information from any given sender.o, if your Anycast DNS network has three name server records-ns1, ns2, and ns3 - each of those corresponds to a group of name servers located in many different geographical regions.
