Open Proxy Ports
What Is the Meaning of Address & Port in Proxy Server Settings?
i Christopher Robbins/Photodisc/Getty Images Proxy servers have uses ranging from protecting corporate networks to helping students bypass school Internet filters. You don’t need to know much about how proxies work, but you may encounter the terms “proxy address” and “proxy port” while surfing the Web. Addresses and ports are terms you need to understand if you wish to configure your browser to use a proxy server. Proxy ServersProxy servers are like telephone operators. They both accept information and route it to the appropriate location. A network administrator, for example, may create a proxy server that sits between the Internet and an organization’s network. The proxy server can then handle all communications between the organization and the Web. Although a proxy server is no substitute for a good firewall, proxies provide some protection from threats coming from the outside world. Free Proxy ServersSearch the Web for “free proxy” and you’ll discover many sites that let others use their proxy servers for free. People who wish to surf privately often do so using free proxy servers. Proxy servers make private surfing possible by preventing websites from determining your IP address. You can begin using the proxy by configuring it in your browser’s settings panel. Your browser’s help explains how to do that. The information that you enter in your settings panel will consist of the proxy server’s address and port. Addresses and PortsA proxy’s address is simply it’s IP number. Every computer on the Internet or other network has a distinct IP number. If you decide to use a free proxy server, the site that provides it will give you the proxy’s address. A proxy’s “port” is a number that refers to a specific virtual location on a computer. Computers have many ports that perform different tasks. When information arrives at a specific port, such as 80, the computer knows how to process that information. Network administrators who set up proxy servers define port numbers and make those numbers available to people who wish to use their servers. ConsiderationsSome people may surf the Web daily without knowing that they are using a proxy server. A business, for instance, might configure all its computers so that they use a company proxy. Microsoft gives an example of setting up a proxy by demonstrating how to enter a proxy’s address and port on Internet Explorer. People and organizations that use proxies can get a proxy’s address and port from a network administrator. If you cannot navigate to a website after setting up proxy server, verify that you entered the address and port correctly when you configured your browser.

Open proxy – Wikipedia
An open proxy is a type of proxy server that is accessible by any Internet user.
Generally, a proxy server only allows users within a network group (i. e. a closed proxy) to store and forward Internet services such as DNS or web pages to reduce and control the bandwidth used by the group. With an open proxy, however, any user on the Internet is able to use this forwarding service.
An open proxy forwarding requests from and to anywhere on the Internet.
Advantages[edit]
An anonymous open proxy is useful to those looking for online anonymity and privacy, as it can help users hide their IP address from web servers since the server requests appear to originate from the proxy server. It makes it harder to reveal their identity and thereby helps preserve their perceived security while browsing the web or using other internet services. Real anonymity and extensive internet security might not be achieved by this measure alone as website operators can use client-side scripts to determine the browser’s real IP address and the open proxy may be keeping logs of all connections.
Most public VPNs work through open proxies.
Disadvantages[edit]
It is possible for a computer to run as an open proxy server without the computer’s owner knowing it. This can result from misconfiguration of proxy software running on the computer, or from infection with malware (viruses, trojans or worms) designed for this purpose. [1] If it is caused by malware, the infected computer is known as a zombie computer.
Testing for access from an open proxy[edit]
Because open proxies are often implicated in abuse, a number of methods have been developed to detect them and to refuse service to them. IRC networks with strict usage policies automatically test client systems for known types of open proxies. [2] Likewise, a mail server may be configured to automatically test mail senders for open proxies, using software such as proxycheck. [3]
Groups of IRC and electronic mail operators run DNSBLs publishing lists of the IP addresses of known open proxies, such as AHBL, CBL, NJABL (till 2013), and SORBS (since 2002).
