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 and keeps a cached version until a new version is published.

Requirements

Python >= 3.10

Tests are verified on Linux, macos and Windows.
