Editing Help:Open proxies (section)

== Open proxy explanation ==
Every computer connected to the Internet has a unique numerical IP address assigned to it. Computers can also indirectly connect to the Internet through other computers; a computer network that allows computers to connect through it is called a proxy server. Such proxy servers can be highly useful, but are usually protected so that only authorized users can make use of them. An open proxy, however, is a proxy that anyone can use freely, by design or due to security vulnerabilities. Such security holes are often present without the knowledge of the owner, as in the case of many badly-configured ISP servers.
