Addressing the Network: IPv4 IPv4 Addresses for Different Purposes
Types of Addresses in an IPv4 Network Range ,[object Object],Network and Broadcast addresses CANNOT be assigned to a host. Network: A special address that refers to the network as an entity . Broadcast: A special address used to send data to all hosts in a network. Host: The unique address assigned to each host in a network.

Types of Communication in an IPv4 Network ,[object Object],[object Object],Unicast: The process of sending a packet from one host to an individual host. Broadcast: The process of sending a packet from one host to all hosts in the network. Multicast: The process of sending a packet from one host to a selected group of hosts.
