asroute

asroute is a CLI tool for parsing traceroute output to summarize AS's traversed.

Ever wondered how your packets get from home to Bhutan? I sometimes like to see it, not at the hop level, but the companies and their networks that carry my data. Or how much shorter the paths are if the site uses a CDN?

Uses Team Cymru's Rust crate for the ASN to AS Name lookup

Notes

The lft tool contains similar functionality and is a feature-rich layer 4 tracing tool (although requires sudo). If you're doing serious network analysis, that is probably more for you. This tool was more to scratch an itch for doing a Rust CLI and seeing how easy (very!) it is to distribute via homebrew.
