ASN
DESCRIPTION
asn is a multifunctional network investigation and OSINT command line tool designed for analyzing Autonomous System (ASN) and IP-related data. It provides a comprehensive set of capabilities for inspecting network infrastructure, routing information, and security signals associated with IP addresses, hostnames, prefixes, and organizations. It aggregates data from multiple external services to present detailed information such as BGP statistics, RPKI validation status, IP reputation, geolocation, and prefix ownership. It can also perform AS path tracing, allowing users to observe the network route between systems and identify Internet Exchange Points or anomalies in the path. In addition to its command line usage, asn can run as a web-based traceroute server or as a self-hosted lookup API that returns JSON-formatted data for automated workflows. This flexibility allows the tool to support manual investigations, incident response, and automated network analysis pipelines.
