 So our original subnet mask was We can quickly convert An octet which is in decimal will be in binary so We will set the first 3 bits of the last octet to 1 and last octet will now be which from the table above will be in decimal. So our new subnet mask is Our third step will be to determine the subnet multiplier which is fairly simple. All we have to do is subtract the last nonzero octet of the subnet mask from We will use the subnet multiplier in the next step to list the subnets.

The first subnet address will be Shown in the table below are the subnet addresses, their respective host ranges and the broadcast addresses. As shown in the table, once we have listed the subnet addresses, calculating the host range and broadcast address is relatively simple.

With the help of a subnetting technique, we can split the large networks of a particular class A, B or C into smaller subnetworks for inter-connection between each node which are situated at different locations. Each node on the network would have a distinctive IP and subnet mask IP. Any switch, router or gateway that connects n networks has n unique Network ID and one subnet mask for each of the network it interconnects with. The formulae of a number of hosts per subnet is as follows:.

We have taken an example of Class C network ID with a default subnet mask. As mentioned earlier, for subnetting in class C network, we will borrow bits from the host portion of the subnet mask. From the above binary notation, we can see that the last 3 bits of the last octet can be used for host ID addressing purpose. With the help of the above example, we can clearly see, how subnetting helps us to construct inter-networking between various links and nodes of the same subnetwork.

Note: Subnet mask is most widely used everywhere in a computer networking system. Hence, there is one more method to represent the subnet mask of a particular network which is chosen and standardized as it is easy to denote and memorize. From the decimal notation we can calculate the number of bits having 1 in each octet:.

With Network ID it can be denoted as From the above notation, anyone who knows the standard notation and formulae of subnetting can understand that the IP is using a subnet mask of As we are denoting the mask scheme while interconnecting the network components through the figure, if we use the decimal and binary method then the overall diagram will become very complex and difficult to understand.

Thus generally, people who are familiar with routing and IP addressing scheme use short notation methods in figures and diagrams. The above figure shows how subnetting is used for interconnection of subnetworks. Each node on the network would have a distinctive IP and subnet mask IP.

## How to Find the IP Address, Subnet Mask & Gateway of a Computer | reispanpankres.tk

The above figure shows how subnetting is used for interconnection of subnetworks. Firstly, as per our need for the number of hosts required to be connected and meet the other requirements of the network, we customize the subnet mask and network ID accordingly and assign to the devices thereafter. Each router has a unique IP address for each linked subnetwork. There is an important point to be noticed that the more the bits we carry from the subnet mask for host ID then the more will be the subnets obtainable for the network.
