Connect to the proxy. If it's a web proxy go to its page in a browser. If it's an HTTP proxy change the network settings in your browser options. Find your new IP address. Using your new proxy connection, visit one of those sites that tell you about your IP address. It might tell you you're now in China.
The software works by creating an encrypted HTTP tunnel between the user's computer and a central pool of proxy servers, enabling users to bypass firewalls and censorship. [9] UltraReach hosts all of its own servers. [9] The software makes use of sophisticated, proprietary anti-blocking technology to overcome filtering and censorship online. [9]
Non-static IP addresses or hosts that are otherwise not permanent proxies should typically be blocked for a shorter period of time, as it is likely the IP address will eventually be transferred or dynamically reassigned, or the open proxy closed. Once closed, the IP address should be unblocked.
Some methods, such as the use of alternate DNS servers, use false addresses or address lookup systems to evade less sophisticated blocking tools while the user accesses the site. [ 1 ] [ 2 ] The drawback of this method is that many censors block the IP address of restricted domains in addition to the DNS, rendering the bypass ineffective.
Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
Privoxy is a "privacy enhancing proxy", filtering web pages and removing advertisements. Privoxy can be customized by users, for both stand-alone systems and multi-user networks. [ 2 ] Privoxy can be chained to other proxies and is frequently used in combination with Squid among others and can be used to bypass Internet censorship .
A Snowflake proxy runs whenever the browser or program is connected to the internet. If the proxy host has a dynamic IP, the proxy will change its IP address over time. [10] [8] See also ad hoc network. Snowflake proxies are thus used as Tor entry nodes, not as exit nodes. Exit nodes are the other end of the chain.
A virtual private network (VPN) service provides a proxy server to help users bypass Internet censorship such as geo-blocking and users who want to protect their communications against data profiling or MitM attacks on hostile networks. A wide variety of entities provide VPN services for several purposes.
