Are you able to flag an IP address as an IP coming from a VPN?

The folks at http://getipintel.net/ can give you some decent information about wether an IP looks spammy or not.

> Given an IP address, the system will return a probabilistic value (between a value of 0 and 1) of how likely the IP is a VPN / proxy / hosting / bad IP. A value of 1 means that IP is explicitly banned (a web host, VPN, or TOR node) by our dynamic lists.

We've been using it for a while and are pretty happy.

Will check this out - thank you.

If you want to know whether an IP is from a VPN, Tor or a compromised server you can do that for free using the Shodan API (https://developer.shodan.io).

Disclaimer: I'm the founder of Shodan and identifying the type of connection is something we're often used for.

Which api method exposes that information?

This is something we'd really like to add to our API and something we're working on.

Are you able to flag if the IP is from a TOR network?

Hi gsqaui, our API now supports detecting Tor nodes https://api.ipdata.co/103.10.197.50

You can see all the datapoints we provide by visiting our homepage https://ipdata.co or by making a call in your terminal via curl https://api.ipdata.co

If you are able to add detection for VPN then this is something my company would happily pay for.

Thank you for sharing your need for this. I'm going to make this a priority. If you'd send me an email jonathan at ipdata dot co, just a quick hello, I could keep you up to date on our progress as we develop this.
