This service provider classifies IPs… It was quite an act to reach anyone from IPQs at all, the background is that many scammers try to blackmail IPQs by means of bad ratings that the IPs are listed positively again. The best way to send a false positive report to IPQs is either to write to the co-founder on LinkedIn or to create an account with IPQs and submit a support request. Also prove that you are the legitimate owner IP and do not belong to a proxy/BotNet. e.g.: Registration number of the company in your own country, screenshots of the server and IP address in the admin panel of the hoster "remove important info!", proof that the local IP is registered to your own company It remains at -2 stars due to the major problems that the whole thing caused. Original problem: This service provider classifies IPs with a score of 99 without any proof or evidence. My e-mail to the False Positive Team and the request for evidence for this classification has not yet been responded to. A check of the IP with other service providers has also not revealed any anomalies. An inquiry to our ISP has also provided no evidence that there is any problem that IpQualityScore claims to have.

Professionals I had to deal with them as my personal IPv4 address kept on being blacklisted by their services. It was quite difficult to get in touch with their support, hence only 4 stars. As soon as I got in touch with them they were willing to assist and help in solving the issue. We are now actively exchanging emails on how to solve the issue and to understand what is causing this blacklisting as they want to improve the quality of their data.

Seems like a nice service, after all There were some initial problems creating an account, but they kindly helped me, and I'm currently reviewing the service's features before deciding on the paid plans. For now it seems like a great deal.

IPQS makes it really easy for our team… IPQS makes it really easy for our team to validate payments and ship orders without worrying about the risk from chargebacks. The support team is also great, and I always get a fast response back. Pricing is very competitive and I have no complaints about the service or accuracy.

Ruins legitimate website traffic Their VPN/proxy detection data service is very draconian and leads to many false positives that ultimately degrade the service experience of many clients I have worked with, who have had their users' residential and cellular IP addresses falsely assigned a high fraud risk. I myself have had several instances where I have been blocked by sites using data from IPQS despite using low risk corporate or residential IPs, needless to say causing endless headache. I would not recommend using this company for proxy detection unless you are looking to alienate legitimate website visitors. Additionally, they are not very receptive to requests to unblock IP addresses and seemingly have an arbitrary and secretive process by which they assign fraud scores.
