A single node in a network is identified by a unicast address. While anycast addresses can be used to identify many targets and transmit packets to the one that is closest, multicast addresses are used to broadcast messages to a collection of nodes. An anycast address, for instance, can be used to deliver a DNS request to a collection of DNS servers.
Sending messages or data from one single node to another uses a form of network addressing called unicast. On the internet, it is the most typical kind of network addressing. Each node on the network is given a distinct address as part of unicast addressing, which is used to distinguish the sender and receiver nodes. The address is used by the sender node to send a message to the receiver node, and by the receiver node to receive the message. The majority of applications use this one-to-one kind of communication. Every form of application, including VoIP, streaming video, and online browsing, uses unicast. Routing protocols and other network administration duties also use it.
