Hide Your IP Address For Secured Browsing



Your right to anonymity

Amendments 4 and 5 of The United States Bill Of Rights protect the right to be free of unwarranted and unwanted government intrusion into one's personal and private affairs, papers, and possessions. Article 12 of The United Nations Universal Declaration of Human Rights states, "No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence, nor to attacks upon his honour and reputation. Everyone has the right to the protection of the law against such interference or attacks."

Despite some charges to the contrary, anonymous Web surfing is not the sole province of criminals. Anonymity also serves whistle blowers, free speech advocates, and people just looking for personal privacy online. Privacy is not a crime and anonymity is not morally ambiguous or wrong, they are your right.

Technical challenges to online privacy

The Internet did not evolve with privacy in mind. In fact, the protocols that provide the fundamental underpinnings of the Internet are inherently non-anonymous. It's just a simple matter of computers needing to know each other's addresses in order to exchange data. For instance, our server has detected your Internet Protocol (IP) address as "59.164.100.213". Other characteristics that a server can detect about you are your referrer (the site from which you are linking), the user-agent (the program you are using to browse the Web), and your operating system.

What does your IP address reveal about you?

Your IP address reveals your point of entry to the Internet and can be used to trace your communications back to your ISP, your employer's network, your school, a public terminal. Though your IP address may not identify you personally, an IP is a unique identifier which represents your computer's digital ID while you are online.

It is possible to disguise your IP address on the Web by using an anonymous proxy server. A proxy acts as an intermediary, routing communications between your computer and the Internet. A proxy specializing in anonymous surfing, however, uses its own IP address in place of yours in every outgoing request.

Approaches to proxy

Proxies are commonly used for several reasons: security, load balancing, data caching in order to reduce bandwidth demands, and censorship or filtering. Filtering proxies insulate you from objectionable elements of Webpages such as cookies, ad banners, dynamic content like Javascript, Java Applets and ActiveX controls. Some anonymous proxies encrypt your Web communications, protecting you from routine monitoring or even dedicated surveillance. Be careful, though, not all proxies are anonymous! Here is an overview of the basic approaches to proxy:

  • Web-based Proxies: Web-based Proxies are powered by server-side softwares such as CGIProxy, PHProxy, Poxy, and custom proxy scripts. These proxies work entirely through a Web browser. Usually all that is needed to hide your IP address and surf anonymously is to visit the service's homepage in a Web browser and enter a URL (website address) in the form provided. There is no requirement to download or install software or reconfigure your computer. To work, a CGI based proxy must manipulate the document you've requested and all its associated elements and objects. This can be tricky, and not all proxies are as efficient or effective as others. Some services are slow and may produce errors while rendering the many variations of Web page code. But they are popular, numerous, and easy to use. See this page for a complete list of Web proxies.

    Proxy.org recommends: Proxify® and the other proxies listed in the top ten.

  • Open Proxies: So-called "open proxies" are HTTP or SOCKS type proxy servers that are accidently or maliciously left "open" and accessible on the Internet. HTTP or SOCKS type proxy servers require that you configure your browser's proxy settings in order to use them. These proxies have the advantage of being compatible with almost all webpages since they do not have to modify the requested page to keep you anonymous. However, there are several major disavantages to using open proxies. Many utilize computers that are compromised, operated by government agencies, or operated by malicious individuals. Often when an attacker obtains control of an end-user's computer they will install a proxy server so the machine can be exploited to launch further attacks on other machines. It is also commonplace for open proxies to be operated as "honey pots", where all actions are logged for forensic research. Open proxies are easy to abuse and there are many people using them to commit credit card fraud, pay-per-click fraud, attack or break into computers, and hundreds of other illegal activities. We strongly discourage the use of open proxies as they provide no privacy or security and using them can result in increased exposure and liability.

    Proxy.org recommends: Socksify® instead of any open proxy.

  • Proxy networks: Various proxy networks (Freenet, I2P, JAP, and TOR) feature layered encryption (sometimes called "onion routing") and peer-to-peer networking to allow their users to communicate anonymously with each other. Rather than operate their own equipment, most rely on end-users to donate bandwidth and other resources to the network. They do not control the servers in their network and certainly a percentage of them are operated by malicious individuals for malicious reasons. Therefore any promises of privacy and security should be evaluated with this in mind. Also, these services have developed a reputation for being relatively slow.

  • Proxy Software: Other subscription-based services offer client-side application software to automatically configure your browser's proxy settings. Do not be fooled by these services as most are merely open proxies dressed up with a fancy interface.
