CIDR Calculator - Online Utility

Subnets:

A CIDR calculator is an online utility that allows you to calculate the network address, broadcast address, and number of available hosts for a given CIDR block. CIDR stands for Classless Inter-Domain Routing, and it is a method for allocating IP addresses more efficiently.

To use a CIDR calculator, simply enter the CIDR block that you want to calculate in the input field. The calculator will then display the network address, broadcast address, and number of available hosts in the output field.

Here is an example of how to use a CIDR calculator:

CIDR block: 192.168.1.0/24

Network address: 192.168.1.0
Broadcast address: 192.168.1.255
Number of available hosts: 254

CIDR calculators can be used for a variety of purposes, such as:

Designing and configuring networks: CIDR calculators can be used to design and configure networks by helping you to determine the appropriate CIDR blocks for your network.

Troubleshooting network problems: CIDR calculators can be used to troubleshoot network problems by helping you to identify the network address, broadcast address, and number of available hosts for a given CIDR block.

Learning about CIDR: CIDR calculators can be used to learn about CIDR by providing you with a visual representation of how CIDR blocks work.

If you are working with networks, then I encourage you to use a CIDR calculator. CIDR calculators can be a valuable tool for designing, configuring, and troubleshooting networks.

If you are looking for a CIDR calculator, there are many different options available. Some CIDR calculators are free, while others require a paid subscription. The best CIDR calculator for you will depend on your specific needs and budget.
