Forced proxy server / transparent proxy

We speak about a forced proxy server if you have to specify a proxy server in your browser (Internet Explorer or Firefox) settings in order to get a connection to the Internet.

Sometimes, the ISP is using a transparent proxy. When using these, you don't have to enter and so also won't find any proxy adresses in your connection settings. You can find out if you are using a transparent proxy by visiting a ProxyJudge website and compare the "REMOTE_ADDR" value with the one you get when you type "ipconfig" in your Dos-Prompt. If its the same, you use no proxy. And if its different you use a proxy. Eiter a "forced proxy" (with the adress and port in your browser settings) or else a transparent one.
