Anonymous proxy

An open proxy server is a server that is capable of processing requests from various IP addresses on the Internet. If the use of conventional proxies can only be accessed by certain trusted persons (often in the area of responsibility of the owner of the proxy server, for example, in a local network), then anonymous proxy servers allow almost all network nodes to communicate through themselves to other network nodes.

Open proxy servers usually mean anonymous proxy servers. They hide the actual IP addresses and therefore ensure anonymous use of Internet network services (participation in chat rooms, forums, visiting websites, etc.). To a certain extent, anonymous proxies are a problem. This is because such anonymity makes it possible, without the risk of punishment, to violate the terms of provision of network services, as well as the law. However, in countries with strict censorship, anonymous proxies are almost the only way to express one's own opinion, even behind a kind of screen.

How do anonymous proxies come about?

An anonymous proxy server can become publicly available at the request of the server owner or due to an incorrect configuration of a regular proxy (an error occurred when verifying the user's address, in the list of broadcast ports in NAT/PAT, or in configuring the "listening" interface).

How are anonymous proxies used?

If the cost of the tariff differs in different networks, an anonymous proxy that is located on "your" network can be used to get more expensive traffic from another network. For example, many domestic users who do not have access to foreign Internet resources at work have the opportunity to obtain such access through an anonymous proxy server. Plus, an anonymous proxy can have its own cache, speeding up the delivery of network resources to the client.

Anonymous proxies can be used to ensure anonymity on the Internet, as they hide the user's IP address by sending user requests from their address. In addition, an anonymous proxy server is able to keep records of requests. You can buy anonymous proxies from us.

Usually, such proxy servers do not provide high-speed information transfer. In most cases, they are used to perform a specific operation. That is, when the fact of the action is important, not the speed.

Bans on anonymous proxies

The user's use of anonymous proxy servers to hide their address may cause some sites to prohibit access to their own resources. For example, anonymous proxy servers cannot be used on Wikipedia, but only for editing the pages of the resource.

An example of an erroneous occurrence of an anonymous proxy server

Suppose that a proxy 192.168.1.2 is installed on the 192.168.0.0/16 network, which has access to the external network via NAT on a router with the external address 100.100.100.100. Requests for IP addresses are not filtered, since only users of the local network have access to this server. If, due to an error, the router allows packets to pass from the external network to node 192.168.1.2 (for example, if the RAT is configured for the web server on node 192.168.1.2, the list of ports is not limited), then when accessing the address for which the RAT is configured (for example, 100.100.100.101, with
the server configured on port 80) according to the proxy port (for example, 8080), any network user has the ability to receive and send data through a proxy, which from now on is considered an anonymous proxy server.
