What is IP Address
In the Network world each devices is identify by the IP address that the identification of each and every computer in the network. The computers are communicate through the ip address over the network. This is defined by the network layer address .At this layer the packet of the communication is also defined identified with the source and destination address of the two end system. With the IP version 4 addresses is 32 bit address which is classified in different class.
IP versions
Two version of Ip address are defined- the first one is IP Version4 and the second is IP Version 6.Each version define the ip address differently.
IP protocol is the network layer that is the layer 3 of the OSI Model that also define the task of routing the data packets and the ip address the location of the source and the destination of the in the topology.
Types of the communications-
Unicast communication and Address
It is a process of sending the packet from one host to another individual packet. This is the normal host to host communication. In Unicast communication the host address assigned to the two end devices are used as the source and destination are used as the source and destination IPV4 address.
Broadcast communication and Address-
It is a process of sending a packet from one host to all hosts in the network. Broadcast and Multicast communication use special address as the destination address. These special addresses are known as broadcast address. There are two types of broadcast address –direct broadcast and limited broadcast.
Multicast communication and Address-
It is design to conserve the bandwidth of the IP V4 network and it help to reduce the traffic by allowing a host to send a single packet to selected set of host. In the Multicast address the source host send the single packet that can be reach thousand of destination host. Example of the Multicast is video and audio broadcast, routing information that is change by some routing protocol like –RIP, IGRP, and EIGRP etc.
