Proxy Type

Below are the list of proxy types supported by IP2Proxy and their definitions.

Proxy Type Description
VPN Anonymizing VPN services. These services offer users a publicly accessible VPN for the purpose of hiding their IP address.
TOR Tor Exit Nodes. The Tor Project is an open network used by those who wish to maintain anonymity.
DCH 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.
PUB 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 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.
SES Search Engine Robots. These are services which perform crawling or scraping to a website, such as, the search engine spider or bots engine.
