Hello Product Hunt community! 👋
I’m the creator of IP Ninja, and I’m thrilled to share it with you all today.
As someone deeply involved in network security, I often found myself frustrated by existing tools. Most Reverse IP services only show what’s currently live, leaving a huge blind spot when it comes to historical infrastructure and past associations. I wanted a tool that didn't just scratch the surface, but offered a deep dive into the 'memory' of an IP address.
That’s why I built IP Ninja. It’s an intelligence-first API designed for security researchers and developers who need high-quality, normalized data without the fluff.
What makes IP Ninja different?
Deep Memory: We don’t just query live DNS; we leverage months of passive collection to show historical hostname-to-IP mappings.
Fully Parsed WHOIS: No more regex nightmares. We return structured JSON for both IP (RIR) and domain data.
Built for Speed: Clean endpoints, simple authentication, and ready-to-use curl examples.
Developer-Centric: A clear dashboard to manage your keys and monitor your usage in real-time.
Whether you are working on threat intelligence, fraud prevention, or just mapping out a complex infrastructure, I built this to save you time.
Happy hunting! 🥷🚀
