With an IPv4 IP address, there are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B, and C What is Multicast? · What is a Localhost? · What is an Internal ip Address?

Since all existing network numbers at the time were smaller than 64, they had only used the 6 least-significant bits of the network number field. Thus it was possible to use the most-significant bits of an address to introduce a set of address classes while preserving the existing network numbers in the first of these classes.
You can tell exactly where someone is if you have their suburb and street name. In the same way, the network ID tells us to which network a particular computer internet protocol classes and the node ID identifies that computer from all the internet protocol classes that reside in the same network.
Classes of IP addresses
Internet protocol classes picture below gives you a small example to help you understand the concept: In the internet protocol classes picture, you can see a small network. We have assigned a class C IP range for this network.
Remember that class C IP addresses are for small networks. Looking now at Host A, you will see that its IP address is I suppose the next question someone would ask is: Class B has Network addresses and Host addresses.
Class B IP address format is: Internet protocol classes C IP addresses range from The default subnet mask for Class C is Class C gives Network addresses and Host addresses. Usually, a unicast address is associated with a single device or host, but a device or host may have more than one unicast address.
Some individual PCs have several distinct unicast addresses, each for its own distinct purpose. Sending the same data to multiple unicast addresses requires the sender to internet protocol classes all the data many times over, once for each recipient.
Broadcast addressing Broadcasting is an addressing technique available in IPv4 to send data to all possible destinations on a network in one transmission operation, while all receivers capture the network packet all-hosts broadcast. In addition, a directed limited broadcast uses the all-ones host address with the internet protocol classes prefix.
For example, the destination address used for directed broadcast to devices on the network IPv6 does not implement broadcast addressing, and replaces it with multicast to the specially-defined all-nodes multicast address.
Multicast internet protocol classes A multicast address is associated with a group of interested receivers. In IPv4, addresses In either case, the sender sends a single datagram from its unicast address to the multicast group address and the intermediary routers take care of internet protocol classes copies and sending them to all receivers that have joined the corresponding multicast group.
