## Historique du projet et usages

asn is a Bash-based network lookup, recon, and traceroute server tool centered on autonomous systems, prefixes, RPKI validity, BGP statistics, geolocation, reputation, and IP/ASN investigation workflows.

### Historique du projet

The nitefood/asn repository was created in July 2020. The README describes a single command-line tool that can also run as a web traceroute server and as a JSON-producing lookup API endpoint.

The project grew beyond simple ASN lookup into a collector of network intelligence APIs and command-line workflows. Its README lists Team Cymru, Prefix Whois, PeeringDB, CAIDA ASRank, RIPEStat, RIPE IPmap, Shodan, Cloudflare Radar, GreyNoise, NVD, IPQualityScore, ipinfo.io, and other data providers as supported inputs.

### Historique d'adoption

asn has unusually broad packaging for a shell network tool. The README displays OS support for Debian, Ubuntu, Kali, CentOS, Red Hat, Rocky Linux, Fedora, Arch, Manjaro, Alpine, openSUSE, FreeBSD, Nix, macOS, Windows environments, and Raspberry Pi, and the input package facts list apk, Homebrew, Debian, Nix, and Ubuntu packages.

GitHub metadata shows roughly two thousand stars and active releases through 2026. Homebrew analytics show continuing installs, while the README's Repology badge points at multi-repository packaging status.

### Modes d'utilisation

The common workflow is to run `asn` against an IP address, hostname, prefix, AS number, URL, or organization name and inspect enriched network output. The tool can do AS path tracing with mtr, RPKI checks, organization searches, Shodan recon, country CIDR mapping, bulk geolocation, and JSON output for pipelines.

Configuration is deliberately Unix-like: defaults can be overridden with `$HOME/.asnrc`, and optional API tokens are read from `$HOME/.asn/` for user mode or `/etc/asn/` for server mode. Docker and Google Cloud Shell workflows are documented for users who do not want a local install.

### Pourquoi les passionnés de paquets s'y intéressent

asn is significant because it packages a messy incident-response habit, asking several network-intelligence services about an address or ASN, into a scriptable CLI. For package maintainers, it is also an instructive case: a Bash tool with many external command and API integrations, distro packages, container usage, and optional credential files.

It occupies the same practical shelf as whois, dig, mtr, bgp.tools shortcuts, and OSINT helper scripts, but makes the package-manager version matter because release updates can add or repair upstream data-provider integrations.

### Chronologie

- 2020: GitHub repository created.
