I appreciate it, sir! If you have any questions or feedback, please let us know.

The challenge of being a data provider is that you can use our data in a million ways, and we don't have coverage of all. So, when you come up with questions or ideas, we can help you better.

As you mentioned, audit logs. I highly recommend you look into the ASN field.

The ASN identifies an organization that owns a block of IP addresses. In my experience, I have found that the combination of ASN+Country is the most valuable information you can use in spam and fraud detection. You can fake the IP geolocation information with a VPN. However, it is not as easy to fake the ASN information of the IP address. So, when you use a combination of country + ASN, you can have a robust cybersecurity system.

Can you explain more how to use ASN to detect fraud and how it's different from the country detected for the IP? I thought ASN was derived from the IP, basically the route to that IP? Here's the ipinfo response for an IP used by a recent fraud signup attempt. The asn field matches country.

Here's the response from ipinfo.io which includes privacy fields. It's technically a proxy but might be hard to detect because it's probably a crowdsourced/botnet proxy not a public one. We don't pay for

    }
  }

EDIT: Oops, I confused ipinfo with ipstack. I'm actually using ipstack. Their security field also doesn't detect this IP as a proxy, which is why we only pay for Professional (no security field).
