A simple CLI program is included to demonstrate range calculation. Run with

`rangecalc`. You can even try it without installation by running `npx rangecalc`.

## Use it

- `getCIDR`: Calculate the CIDR range of two IP addresses.

- `getInt`: Calculate an integer representation of an IP address.

- `sort`: Sort an array of IP addresses.

More information on the functions available can be found [here](https://clpo13.github.io/rangecalc-js).

## Improve it

Install the devDependencies with `npm install`. Run tests with `npm test`. Pull requests are more than welcome.

## To do

- [ ] Show how many addresses are in a range

- [ ] Calculate IPv6 addresses
