The information includes, but is not limited to:

-   ISP (Internet Service Provider)
-   geographical location of the IP address (city-level / postal code accuracy)
-   s IP blacklisted (various malware and anti-fraud blacklists)?
-   Does the IP address belong to a public proxy / VPN or Tor browser?

## How can you use this information?

With ClickGuard, all information about an IP address is made actionable through automated rules. You can set different thresholds for different combinations of conditions.
