# digaws

The digaws lookup tool displays information for a given IP address (v4 o v6) or a CIDR, sourced from the AWS official IP ranges.
In order to save bandwidth and time this tool requests the [AWS IP ranges](https://ip-ranges.amazonaws.com/ip-ranges.json) and keeps
a cached version until a new version is published.

## Install

```bash
pip install digaws
```

## Usage

```bash
usage: digaws [-h] [--output <plain|json>] [--debug] <ip address|cidr> [<ip address|cidr> ...]
