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
