IPv4 addresses were initially intended to be classful- ranging from Class A to Class E. Here subnet mask is 255.255.255.0, so 192.168.100.0 will become Network Address, and the Host Address will become 0.0.0.1 What is Classless and Classful Ip addressing, and what is the difference? When you put the IP address and the subnet mask together, you can separate the network and host parts of the address. These 32 bits are further split into four sections. Therefore, both types of addresses are always used in conjunction and have a length of 32 bits. The subnet mask divides the IP address into the host and network addresses, defining which parts belong to the device and which to the network.Īn IP address and a subnet mask provide complete information and numerical identification to any device connecting to the network. Unicast IP addresses are the most common type and are found on our laptops or other devices to connect to the Internet.

IP addresses can be broken down into three categories, namely unicast (used on individual devices), multicast (allows someone to send information to a group of computers), and broadcast (which allows one computer to send information out to everyone).

Each octet represents 8 bits or 1 byte, and when you multiply by 4, it will give 8×4=32 bits.

Three dots separate this 32-bit number, and four blocks we call octets.

It is a 32-bit binary number representing a specific physical location on the network.

But, first, let’s understand a few needy greedy things about IP addresses. What is an IP address? IP Address ExplainedĪn IP address is a unique identifier for every computer, server, router, and hardware that connects to the network. More on this later let’s first understand IP address and other important concepts related to subnetting. Subnetting is widely used to preserve IP addresses and design scalable and secured networks. IP Subnetting splits a network into multiple sub-networks, creating a partition based upon a consecutive block of IPv4 addresses, further represented by an IP address and the subnet mask. What is IP subnetting, and why do we need it?
