asnmap is a Go CLI tool and library that maps organizations to their network ranges (CIDR blocks) using ASN information. It supports lookups by ASN, IP, domain, or organization name, with JSON/CSV/text output and stdin/stdout piping.
Use cases
- find all IP ranges belonging to an organization
- map ASN to CIDR blocks for reconnaissance
- resolve a domain to its network ranges
- enumerate attack surface from an org name
- look up CIDR ranges for an IP address
- pipe ASN data into other recon tools
When to choose
- you need quick ASN-to-CIDR mapping during OSINT or recon
- you want a scriptable CLI with JSON/CSV output and stdin support
- you need a Go library for ASN lookups in your own tooling
When to avoid
- you need deep BGP routing analysis or historical ASN data
- you want a GUI-based network mapping tool
- you need real-time network monitoring rather than one-off lookups
