"Ultimate availability for your zone"
Anycast technology allows having the same IP address reachable on multiple geographic locations around the globe. Routing protocols on the Internet ensure that a request reaches the topological closest instance of the anycast cloud. Latency is minimized by that and, what’s more, traffic is distributed on the various locations (nodes).
In particular in the case of an DoS attack on the nameserver network, only the closest node is affected and the others operate unaffected. Furthermore, since the whole anycast DNS network only utilizes one IP address, DNS packets stay smaller compared to multiple unicast instances (just a single NS record is contained in the delegation).
THE ANYCAST TECHNOLOGY
The classical addressing method in the Domain Name System is unicast; a DNS server has a dedicated IP address. Queries to this IP address all lead to this one server no matter where in the world the client is located.
This may cause delays and timeouts for remote clients. Furthermore, if the server is down or a victim of a DoS attack, the whole service provided under this dedicated IP address is affected and not available anymore.
