Open proxy
open-in-new
<p>An open proxy is a type of <a href="/facts/Proxy_server/ArhwQE74">proxy server</a> that is accessible by any <a href="/facts/Internet/Xw1rVvJU">Internet</a> user. </p><p>Generally, a proxy server only allows users within a network group (i.e. a closed proxy) to <a href="/facts/Store_and_forward/zwM8Amlv">store and forward</a> Internet services such as <a href="/facts/Domain_Name_System/rfxdWFsj">DNS</a> or <a href="/facts/Web_page/5JK7xQLe">web pages</a> to reduce and control the <a href="/facts/Bandwidth_(computing)/lY6Tb4gX">bandwidth</a> used by the group. With an open proxy, however, any user on the Internet can use this forwarding service. </p>
