By known do you mean public proxy? Or are you after the proxy software?

Chris

Im trying to establish if an IP comes back to a proxy server, public or otherwise. There are apps that hide the real IP address, Im trying confirm or deny that is the case. There are sites that check IPs for this but it has to be in <b>IP:port</b> format.

Check IP Address - Proxy Server?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
