What problem does it solve?

This Skill solves the problem of incomplete IP infrastructure discovery during reconnaissance, where standard subdomain enumeration misses IPs hosted on sibling top-level domains, separate ASNs for subsidiaries or acquired entities, and services running on non-standard ports.

Core Features & Use Cases

  • ASN & CIDR Range Extraction: Pivot from target domains or known IPs to extract full CIDR ranges owned by the organization via ASN lookup.
  • TLD Expansion: Discover sibling domains on alternate top-level domains that may host separate, less secure infrastructure.
  • Infrastructure Mapping: Perform reverse DNS on IP ranges, scan for live web services, and visualize the full domain-to-IP-to-service architecture.
  • Use Case: For a target with only 3 known subdomains, use this Skill to uncover 200+ additional IPs across their ASN, find 12 live services on non-standard ports, and identify 4 sibling domains on .io and .dev TLDs to expand the reconnaissance scope.

Quick Start

Use the asn-infrastructure-mapping skill to map all IP infrastructure, CIDR ranges, and live services for the target domain example.com.
