In today's society, the Internet has become an indispensable part of people's lives. It provides us with convenient channels for information acquisition, communication and entertainment.

However, some countries and regions block the Internet and restrict people's online freedom for various reasons such as political, economic, and cultural. This brings a lot of inconvenience to people's lives, but we can break through the network blockade and protect our network rights by using proxy servers.

First, we need to understand what a proxy server is.

A proxy server is a computer located in a certain network. It can act as a transfer station between the client and the target server, forwarding requests from the client to the target server, and forwarding the data returned by the target server to the client. . By using a proxy server, users can hide their real IP address, thus protecting their privacy.

So, how to use a proxy server to break through network blockade?

We can break through the network blockade through a proxy server. Users can access blocked websites by setting the IP address and port number of the proxy server in their browser.

Additionally, there is another way to access blocked websites by using the Tor browser. Tor Browser is an anonymous browser that hides the user's true IP address by forwarding the user's web traffic to different servers through multiple layers of encryption. Users only need to download the Tor browser to access blocked websites in blocked countries or regions.

In addition to using proxy servers, we can also use other methods to break network blockades.

For example, use SSH (Secure Shell Protocol) tunnels to access blocked websites. An SSH tunnel is an encrypted channel that forwards a user's network traffic to a remote server and decrypts and forwards the data on the remote server.

Users can set up an SSH server locally and then connect to the remote server through an SSH client to access blocked websites.

Additionally, blocked websites can be accessed by changing the DNS (Domain Name System) servers. The DNS server is responsible for converting URLs into IP addresses to enable website access. Some blocked countries or regions restrict access to specific DNS servers, so users can set the DNS server to other available DNS servers to bypass the block.

In general, using a proxy server is an effective way to break through network blocks. By choosing a suitable proxy server, we can easily access blocked websites and protect personal privacy and network security.

However, it should be noted that there are certain risks in using a proxy server, so we need to choose a reliable service provider and do not transmit sensitive information online.
