such as VPN anonymizer (VPN), open proxies (PUB), web proxies (WEB), Tor exit nodes (TOR) and data center ranges (DCH).
For evaluation purpose, you can enter 22.214.171.124 for a known DCH IP address range.

Below are the list of proxy types supported by IP2Proxy and their definitions.
||Anonymizing VPN services. These services offer users a publicly accessible VPN for the purpose of hiding their IP address.
||Tor Exit Nodes. The Tor Project is an open network used by those who wish to maintain anonymity.
||Hosting Provider, Data Center or Content Delivery Network. Since hosting providers and data centers can serve to provide anonymity, the Anonymous IP database flags IP addresses associated with them.
||Public Proxies. These are services which make connection requests on a user's behalf. Proxy server software can be configured by the administrator to listen on some specified port. These differ from VPNs in that the proxies usually have limited functions compare to VPNs.
||Web Proxies. These are web services which make web requests on a user's behalf. These differ from VPNs or Public Proxies in that they are simple web-based proxies rather than operating at the IP address and other ports level.
