# CIDR calculator for CLI
Calculate Network Ranges for a given CIDR.
For example, 10.122.33.44/24 prints out the following information:
```
Subnet mask: 255.255.255.0
First usable IP: 10.122.33.1
Last usable IP: 10.122.33.254
Broadcast IP: 10.122.33.255
```
**CIDR** stands for **Classless Inter-Domain Routing**. Learn more about CIDR [here](https://aws.amazon.com/what-is/cidr/)
