Recommend me some good services for detecting VPN, proxy or datacenter IPs
I need some recommendation for free or paid (not so expensive though) service which can detect majority VPNs, proxies or IPs coming from datacenters.
I already checked maxmind official site and they have something like this:
As you can see they only do that for enterprise-level applications and is subject to custom terms and pricing.
Is there any service which provide this? How could I detect this cost effectively?
