IP2Proxy™ Proxy Detection Database contains IP addresses which are used as VPN anonymizer, open proxies, web proxies and Tor exits, data center, web hosting (DCH) range and search engine robots (SES).
Anonymous proxy servers are intermediate servers meant to hide the real identity or IP address of the requestor. Studies found that a large number of anonymous proxy users are generally responsible for online credit card fraud, forums and blogs spamming.
IP2Proxy™ database is based on a proprietary detection algorithm in parallel with evaluation of anonymous open proxy servers which are actively in use. Then it generates an up-to-date list of anonymous proxy IP address in the download area every 24 hours. Web developers can automate the download process once a day from our server and import the anonymous IP address list into their server using download scripts. If you prefer a hosted service, you can subscribe to the IP2Proxy Proxy Detection Web Service.
This is a database subscription service. You can download all daily updates for free while your subscription is active.
