## What it is
A Bash-based command-line tool and self-hostable server for looking up ASN, RPKI validity, BGP stats, IP prefixes, AS paths, IP reputation, geolocation, and fingerprinting. It can also run as a web-based lookup/traceroute server and a JSON API.

## Use cases
- look up the ASN and organization behind an IP address
- check RPKI validity of a prefix
- trace an IP's AS path and BGP stats
- get IP geolocation and reputation for incident response
- run a web traceroute server for my team
- query ASN data via a JSON API
- fingerprint an IP during network recon

## When to choose
- you need quick CLI-based ASN/IP intelligence without a heavy stack
- you want a self-hosted lookup or traceroute server
- you're doing OSINT or incident response on network infrastructure

## When to avoid
- you need a programmatic library to embed in an application
- you need real-time BGP feeds or full routing tables
- you need a GUI-based network analysis tool
