Unicast vs Multicast vs Broadcast Address
#Summary - In today's blog we will learn about Unicast, Multicast and Broadcast different type of IP Addresses.
#Unicast IP Address -
*Unicast means one to one communication.
*When a data packet is sent from a host with destination address which represents a single host, a Unicast communication takes place.
*Hence, A Unicast IP Address is an IP address which uniquely identifies a host in a particular network.
*On the Internet each host has at least one unique Unicast IP Address.
*These addresses belongs to Class-A, Class-B, Class-C
*Example of Unicast IP Address - 192.168.1.22
#Multicast IP Address -
*Multicast means one to many communication.
*When a data packet is sent from a host to a group of hosts, a Multicast communication takes place.
*Multicast addresses belongs to class D addresses and these addresses define an address for a group.
*A System on a Multicast Network can have more than one class D Multicast addresses.
*If a system has five multicast addresses, then the system belongs to five different multicast group for Example - 224.0.0.1 is a Multicast address
#Broadcast IP Address -
*Broadcast addressing means one to all communication.
*A Broadcast address is an IP address that allows a data packet to be sent to all machines on a given network.
*Data Packet is broadcast only at local level and not at Global level
*In some applications the hosts in a network need to send message to all the hosts in a network. For example transmitting information such as weather report, stock market change and live radio programs would work best by broadcasting the data over the network to all the hosts.
