Routing via Unicast
The sending of messages to a single network destination identified by a unique address.
Routing via Anycast
Communication between a single sender and the topologically closest instance of a network service with a common IP address.
Using Hybrid Routing
In a hybrid solution, a smaller number of name servers within a zone is anycasted, while the remaining servers are unicasted.
