Today, in this article, we show how to calculate subnet masks in Linux with ipcalc. Adding a subnet to a large network increases security, increases performance, and logically organizes your network. However, some calculations are challenging. ipcalc for Linux Simplifies the planning process.
Subnetting is a technique for slicing up a large network into manageable, interconnected chunks. A subnet is the name of each segment. You can decide to set up your network so that different departments such as sales, HR, and customer support use a different subnet. This has many advantages. The first has to do with control and security. Everything is a single large “flat” network with no subnets.
You can select which subnets can communicate with other subnets using the subnet. We’ll discuss subnet masks a little later, but many subnets employ different IP address ranges. Traffic from one subnet must be able to reach another subnet, so your router must be configured up to support this. A router also allows you to control the type of traffic and interaction allowed between multiple subnets because it is a managed device. We mentioned below the steps to calculate subnet masks in Linux with ipcalc.
Steps to Calculate Subnet Masks on Linux with ipcalc
Installation
Step 1: To install Ipcalc on Ubuntu/Debian based Linux, open the terminal and run the following command:
$ sudo apt-get install ipcalc
Use Ipcalc
Step 1: Use ipcalc to find out everything you need to know about your IP address:
$ ipcalc 192.168.1.27
Calculate a subnet
Step 1: To calculate the subnet for 192.168.1.0/24, use the following command:
$ ipcalc 192.168.1.0/24
Calculate a single subnet with 5 hosts
Step 1: To calculate a single subnet, use the following command:
$ ipcalc 192.168.1.0 -s 5
Calculate multiple subnets using a single command
Step 1: Suppose you want to split 192.168.1.0 into three subnets, with a total of 50 hosts. On each segment, specify its netmask and the number of hosts.
$ ipcalc 192.168.1.0 -s 10 20 20
Final Words
We hope you like our article about how to calculate Subnet Masks on Linux With ipcalc. Subnets can also prevent malware and unwanted users from anonymously roaming your network. At the very least, it will make them slower. Imagine it as a submarine.
You can close the bulkhead doors if there is a hull breach in one of the sections to prevent the rest of the ship from sinking. Subnets resemble the doors that separate rooms. Subnetting a large network often has positive effects on performance. This performance boost will come from decreasing network traffic on each subnet if your network is large and busy enough.
