OSINT IP Address Intelligence: IP Geolocation & Threat Analysis

Overview#

An IP address is one of the most common starting points in a security investigation, and also one of the most misread. An IP that appears to originate from Germany may belong to a VPN exit node with subscribers in a dozen countries. A datacenter IP that looks like a cloud provider may be hosting botnet command infrastructure. Getting the context right, geolocation accuracy, hosting type, anonymization status, and threat history, determines whether an analyst treats a log entry as noise or pursues it as a lead. IP Address Intelligence brings that context together from multiple sources, in real time.

The platform supports both real-time lookups and bulk analysis for security operations, fraud prevention, and investigative intelligence across IPv4 and IPv6 space worldwide.

Key Features#

• IP Geolocation: Multi-source geolocation providing continent, country, region, city, postal code, and coordinate-level positioning with accuracy radius estimates for both IPv4 and IPv6 addresses
• ASN and Network Intelligence: Autonomous System Number identification, network ownership, IP range allocation, peering relationships, and hosting provider classification
• Threat Reputation Scoring: Composite risk assessment based on malware activity, spam origination, botnet participation, attack history, and correlation with threat intelligence feeds
• VPN and Proxy Detection: Identify VPN services, proxy servers, Tor exit nodes, residential proxies, and datacenter hosting to assess anonymization and true origin
• Historical IP Intelligence: Track IP address usage changes, hosting migrations, reputation changes, and historical threat associations over time
• Abuse and Blocklist Checking: Cross-reference against major blocklists, abuse databases, and reputation services to identify IPs with known malicious activity
• Hosting Classification: Distinguish between residential, commercial, datacenter, mobile, and cloud hosting to inform risk assessment and fraud detection
• Bulk Analysis: Process large IP address lists for threat hunting, log enrichment, and security operations with automated enrichment and risk scoring

Use Cases#

• Threat Investigation: Analyse IP addresses associated with attacks, malware campaigns, or suspicious activity to identify geographic origin, hosting infrastructure, and threat actor patterns
• Fraud Detection: Assess transaction risk by evaluating IP geolocation against claimed user location, detecting VPN/proxy usage, and checking threat reputation
• Incident Response: Rapidly enrich IP-based indicators of compromise with geolocation, network ownership, hosting details, and threat intelligence during active incidents
• Access Control: Inform geographic access policies and anomaly detection by identifying connection origins, flagging unexpected regions, and detecting anonymization attempts
• Log Enrichment: Augment security logs and network traffic data with geolocation, ASN, and reputation context for enhanced threat detection and forensic analysis

Integration#

The platform integrates with the broader Argus OSINT ecosystem for cross-domain intelligence correlation, SIEM platforms for log enrichment, threat intelligence feeds for reputation data, and fraud prevention systems for transaction risk assessment. IP intelligence works alongside Shodan for service-level exposure data, GreyNoise for noise classification, and SpiderFoot for automated follow-on OSINT. Indicators export via STIX/TAXII to OpenCTI and MISP for community sharing. Supports all 153 third-party integrations available through the Argus provider orchestration layer.

Open Standards#

• STIX 2.1 (OASIS CTI TC): IP addresses are modelled as ipv4-addr and ipv6-addr Cyber Observable Objects inside STIX Indicator SDOs, enabling bidirectional export to OpenCTI and MISP for community sharing.
• TAXII 2.1 (OASIS CTI TC): Analyst-configured feed subscriptions poll TAXII 2.1 collections to ingest IP threat intelligence, with each subscription explicitly tied to an initiating analyst identity.
• MITRE ATT&CK: Threat actors linked to IP addresses are scored against the MITRE ATT&CK technique and tactic catalogue, with technique IDs (e.g. T1583) used as structured attribution evidence.
• RFC 791 (IPv4) / RFC 4291 (IPv6): The platform covers both address families across all enrichment, reputation, and geolocation workflows, with explicit branching on STIX ipv4-addr and ipv6-addr object types.
• BGP Autonomous System Numbers (IANA ASN Registry): ASN, organisation name, and CIDR route data are stored per the IANA Autonomous System Number registry and sourced from MaxMind GeoLite2, underpinning network ownership and hosting classification.
• WHOIS (RFC 3912): IP registration and abuse-contact lookups are performed against WHOIS services to retrieve network ownership records and blocklist correlation data.
• GeoJSON (RFC 7946): Geolocation output including latitude, longitude, and accuracy radius is stored and served in GeoJSON-compatible format, enabling downstream mapping and geofencing workflows.
