About

GreyNoise runs sensors across the internet that watch mass scanning and opportunistic attacks, so it can tell you whether a suspicious IP is just background noise (a known scanner, search engine, or benign service) or something that has never been seen scanning. Which could mean it's targeting you specifically. The free Community API needs no key for basic use and returns a simple verdict: noise, riot (known benign service), or not seen. A free account raises your allowance.

Setup

  1. No signup needed to try it: paste an IP onto the example URL in your browser.
  2. Read 'noise' (mass scanner), 'riot' (known benign service), and 'classification' fields.
  3. For more lookups, create a free account on the Visualizer and use your API key in the 'key' header.
  4. Treat 'not seen' results as potentially targeted. Investigate those first.
