GreyNoise IP Check

[Skhilled]

I thought that this was interesting. When you go to the site, it checks your IP address for any malicious activity:

GreyNoise watches the internet's background radiation—the constant storm of scanners, bots, and probes hitting every IP address on Earth. We've cataloged billions of these interactions to answer one critical question: is this IP a real threat, or just internet noise? Security teams trust our data to cut through the chaos and focus on what actually matters.

Their search page to search IP's in different ways:

A REST API:

They also have a Blocklist, although, it's paid:

And a lot of other information.
