« on: 05-23-2010, 17:39:38 »
I know how to whois an IP and various other tools to look into IP's but how do you tell if an IP is that of a proxy?

Is there anyway at all to find out?

There are a number of possibilities not only to detect a visitor using several anonymous proxy servers, but also to detect his real IP even if he is using an anonymous proxy server.

You cannot detect IP with the help of cookies. However, when you first visit a web site, the IP (i.e. your proxy server s IP) is detected by the web server and then stored in the cookies.

ActiveX and plug-ins are various add-ons and modules of your browser. These modules are in fact real proper programs run on the client s machine and therefore they have wider capacities than Java and Javascript. They can easily detect your browser settings and track down your real IP address.
