# digaws
The digaws lookup tool displays information for a given IP address (both v4 and 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.
