# AsnRecon Discover a company's network footprint by finding their ASNs and owned IPv4 ranges using bgp.he.net. **Why This Matters:** Companies often own IP space that isn't discoverable through DNS. Finding ASNs and IP ranges reveals infrastructure that subdomain enumeration misses - data centers, cloud deployments, legacy systems, and internal networks. ## Workflow Routing **When executing a workflow, output this notification directly:** ``` Running the **WorkflowName** workflow from the **AsnRecon** skill... ``` | Workflow | Trigger | File | |----------|---------|------| | **FindAsn** | "find ASN", "ASN lookup", "company ASN" | `workflows/FindAsn.md` | | **FindIpRanges** | "find IP ranges", "IPv4 prefixes", "owned IP space" | `workflows/FindIpRanges.md` | | **FullAsnRecon** | "full ASN recon", "network footprint", "all IP ranges" | `workflows/FullAsnRecon.md` | ## Examples **Example 1: Full ASN reconnaissance (RECOMMENDED)** ``` User: "Find the IP ranges owned by Acme Corp" → Invokes FullAsnRecon workflow → Searches bgp.he.net for "Acme Corp" → Identifies all ASNs associated with the company → Extracts IPv4 prefixes from each ASN's Prefixes V4 tab → Outputs {company}-asn-report.md with all ranges → User has complete network footprint for testing ``` **Example 2: Find company's ASN numbers** ``` User: "What ASNs does Netflix own?" → Invokes FindAsn workflow → Searches bgp.he.net free-form for "Netflix" → Lists all ASN numbers with organization names → Outputs ASN l
