SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Investigate and document ownership, infrastructure, and reputation of an IP address using passive public sources to avoid active scanning.

Core Features & Use Cases

  • Passive data collection from ipinfo, RIPE NCC, ARIN, APNIC, LACNIC, AFRINIC, MXToolbox, VirusTotal, AbuseIPDB, and Shodan to build a comprehensive IP profile.
  • Structured report including ownership, ASN, geolocation, reverse DNS, reputation, related infrastructure, and historical context.
  • Use Case: Incident response, threat intelligence, and due-diligence investigations across corporate networks, cloud assets, and partner ecosystems.

Quick Start

Provide an IP address or CIDR range to generate a passive IP intelligence report.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I perform a passive IP intelligence investigation?

Passive IP intelligence investigations collect ownership, ASN, geolocation, and reputation data without active scanning. This Skill queries ipinfo, RIR registries, VirusTotal, AbuseIPDB, and Shodan to build a comprehensive profile for incident response and due diligence.

What is passive IP reputation lookups used for in threat intelligence?

Passive IP reputation lookups identify malicious infrastructure and summarize IP ownership for threat intelligence. They apply to incident response and due-diligence tasks across corporate networks, cloud environments, and partner ecosystems without alerting targets.

Can I check IP geolocation and ASN ownership using public registries?

Yes, you can check IP geolocation and ASN ownership using public registries. This Skill aggregates data from ipinfo and RIR registries like RIPE NCC, ARIN, APNIC, LACNIC, and AFRINIC to accurately identify hosting infrastructure and network ownership.

Does passive IP research work with CIDR ranges?

Yes, passive IP research works with CIDR ranges. You can provide an IP address or a CIDR range to generate a structured report covering reverse DNS, related infrastructure, and historical context for the specified network block.

What is the difference between passive IP intelligence and active network scanning?

Passive IP intelligence relies on querying existing public sources like Shodan and AbuseIPDB, whereas active scanning sends packets directly to targets. Passive methodology avoids detection, making it safer for incident response and partner due-diligence.

When should I not use passive IP reputation data for incident response?

Passive IP reputation data may be insufficient when you need real-time vulnerability status or live service banners. It relies on historical and third-party data from sources like MXToolbox and VirusTotal, which might not reflect instantaneous network changes.
