So, if we divide this large network into the smaller network then maintaining each network would become easy. Subnet mask has binary is in all bits specifying the network and subnet-work. To manage such a large number of hosts is a very difficult job. Subnet mask uses the same format and representation technique as IP addresses. This process, called subnetting, uses the host section of the IP address to break it down into those smaller networks or subnets. Generally, we divide the network into smaller networks or subnets which is called subnetting. The main features of subnet are as follows − This technique makes the network routing an efficient one. It is a smaller network inside a large network. Subnet (sub network)Įvery website needs a unique IP address, in order to uniquely identify the website, we are dividing the IP network into two or more networks called subnet, which is preferred to control network traffic. In this way, we set the host bits to zero in the Subnet mask. Suppose we have a subnet address as 192.168.1.0. It tells us about the IP of the host which has done subnetting. The binary "0" in the subnet mask tell us about the host address. Within a given network, two host addresses are reserved for a special purpose, and cannot be assigned to hosts. ![]() Subnet Mask is made by setting the network bits to all "1"s and setting host bits to all "0"s. It divides the IP address into multiple parts which can be assigned to every computer. ![]() Subnet Mask is used in networking to create multiple sub networks in a network.
