For example a.b.c.d is a generalized IPV4 address where values of a, b, c and d can vary from 0 to 255.įor example 172.01.85.56 is an IPV4 address. In IPV4, the number of bits is 32 which are divided into 4 parts by dots. IP addresses are classified in two types: The IP address is a numerical value that is unique, and it represents the unique node(computer) in the network. The full form of IP is “Internet Protocol”, which means set of rules for the internet. The most common use of loopback addresses is to recognize the device on the network. When the destination is a loopback address for any packet, then the message is received by the same machine as it is destined to itself. The loopback address is used by the operating system to test the software in the local machine. In computer networks, the range for loopback addresses is 127.0.0.0 to 127.255.255.255. The loopback address in IPv6 is either 0:0:0:0:0:0:1 or::1. In IPv4, the loopback address is 127.0.01. It is a local system's internal address and routes there. You're presumably already acquainted with the loopback address, often known as localhost. If the destination IP address is 21.0.0.0 then to transmit data, all the hosts present in this network sender will send the data to the address 21.255.255.255.255. If the sender wants to send the data to all the hosts present in another network then this is called direct broadcasting. As we broadcast the message then all the nodes and the router connected to this network will receive the message in the form of packets. Now, as source we will consider source 1 and in destination we will put the IP address as 255.255.255.255. Let's suppose the IP address of source 1 is 10.1.1.11 If we want to consider the local broadcast in this network, then we will send the data to all the sources from one node. Local broadcast address is 255.255.255.255, and in the binary form, it isįor example, let's consider a network where 4 sources ( source1, source2, source3, and source4) are present. So in IPV4, the address is reserved for all the local broadcasts, and it is called the local broadcast address. When receiver hosts are in the same network as the transmitter network, then this is called local broadcasting.įor local broadcasting, the sender needs the IP address of all the receiver hosts. It is also called one-to-many communication. Radio channels broadcast their songs to a particular channel, and all the people on that channel can easily listen to those songs.Īnother example of broadcast is the TV channels when these channels broadcast their shows with the help of satellites, then every device that can access these channels can see their shows. One of the popular examples is radio channels. When one host sends the data to all the other hosts present in the same network or another network then this is called broadcasting. This is also referred to as one-to-one communication. So there is a direct transmission of data from one source to another source. The source host needs the IP address of the destination host, and then it can easily send the data in the form of packets.įor example, when we request some data from a hyperlink, the requested data is only received by the server on our local computer. In Unicast, the number of sources and destinations is always one. When in a network, one host sends the data to another host in the same or different network then this is referred to as Unicast. We can categorize the casting upon the number of receiver sources which are following: In computer networking, if you send the data from one source to another source or group of sources in the form of packets, then this is called casting.
