The cidr package provides a Go utility for converting CIDR (Classless Inter-Domain Routing) blocks into a range of numeric IP addresses. It is designed to work specifically with IPv4 addresses and is useful for network-related operations such as checking if an IP address falls within a CIDR range.

The cidr package provides a Go utility for converting CIDR (Classless Inter-Domain Routing) blocks into a range of numeric IP addresses. It is designed to work specifically with IPv4 addresses and is useful for network-related operations such as checking if an IP address falls within a CIDR range.

Features

• Convert CIDR blocks to numeric IP address ranges.
• Handle IPv4 addresses.
• Simple and easy-to-use API.

Installation

Note

This requires go1.22.1+. The reason it's not supported on older versions (e.g, go1.21 or lower) is because go1.22+ supports range over integers. If you're advanced in Go, you can easily perform mass checking using multiple goroutines or a single goroutine.

To install the cidr package, you need to have Go installed on your machine. Use the following go get command to retrieve the package:

go get github.com/H0llyW00dzZ/cidr
