What is Unicast?

There are 3 main methods of data transmission in IP networks: Unicast, Broadcast, Multicast. 

• Unicast – the process of sending a packet from one host to another host. Unicast works in client-server and peer-to-peer networks.

• In unicast packets, the specific IP address of the device for which this packet is intended is used as the destination IP address. The IP address of a particular device consists of a portion of the network address (in which this device is located) and a portion of the host address (a portion that defines this particular stable in its network). This all leads to the possibility of routing unicast packets throughout the network. 

• In unicast IP networks, an address is an address, that is, the address of an end device (for example, a computer). For the unicast data transfer type, host addresses are assigned to two end devices and used (these addresses) both the source IP address and the destination IP address.
