IP Ninja – OSINT & Network Intelligence API
Overview
IP Ninja is a cybersecurity and OSINT API designed to provide deep intelligence about IP addresses and internet infrastructure. It enables security professionals, researchers, and developers to analyze IP-related data through a powerful set of lookup endpoints.
The platform offers capabilities such as reverse IP lookup with historical data, WHOIS records, DNS queries, IP geolocation, ASN lookup, and reverse ASN search. By combining passive DNS collection with active probing techniques, IP Ninja provides fast and comprehensive insights into how domains, IPs, and networks are interconnected.
The API is built for automation and can be easily integrated into security tools, monitoring systems, and threat intelligence pipelines.
Key Features
Reverse IP Lookup
Discover domains hosted on a given IP address. Unlike traditional PTR lookups, IP Ninja uses a large database built from passive and active DNS data to provide broader and historical results.
Historical IP Intelligence
Access historical associations between domains and IP addresses to understand infrastructure changes over time.
WHOIS Lookup
Retrieve registration information about domains and network ownership.
DNS Lookup
Query DNS records to analyze domain configurations and infrastructure.
IP Geolocation
Identify the geographical location and hosting environment of an IP address.
ASN Lookup
Get detailed information about the Autonomous System responsible for an IP range.
Reverse ASN Lookup
Find all IP ranges associated with a specific ASN to map network infrastructure.
Developer-Friendly API
REST API designed for easy integration with scripts, applications, and security platforms.
Use Cases
Threat Intelligence
Investigate malicious infrastructure by identifying domains hosted on suspicious IP addresses.
Incident Response
Analyze attack sources and correlate IP addresses with domains, networks, and hosting providers.
OSINT Investigations
Gather publicly available intelligence about internet infrastructure for research and investigations.
Infrastructure Mapping
Understand relationships between domains, IP ranges, and networks.
Security Automation
Integrate IP intelligence directly into SIEM, detection systems, or monitoring tools.
Getting Started
- Create an account on the IP Ninja platform.
