Website Blocking: How to Resolve It

Overview

The internet is an open, free, and diverse space that allows us to access various websites and content. However, sometimes we may find that certain websites we want to visit are blocked, making it impossible to access or display them. This can cause inconvenience and frustration in our studies, work, or leisure.

Reasons and Methods of Website Blocking

Websites may be blocked for reasons related to politics, law, business, copyright, morality, etc., and different countries or regions may have different standards and regulations. For example, some countries or regions may block websites related to sensitive political topics or opposition for the purpose of safeguarding national security or social stability. Some countries or regions may block websites involving pornography, violence, gambling, or copyright infringement to comply with laws or protect intellectual property. Others may block foreign or competitive websites to promote the local economy or gain a competitive advantage.

There are primarily four methods of website blocking

① IP Address Blocking

This involves blocking a target website's IP address to prevent users from accessing it. An IP address is a unique identifier for each website on the internet, similar to a phone number. When a user enters a website address, the browser converts it to the corresponding IP address through the Domain Name System (DNS) and then connects to the target website using that IP address. If the IP address of the target website is blocked, users cannot establish a connection to that website.

② DNS Spoofing

This method involves tampering with the domain name-to-IP address mappings stored on DNS servers to mislead users into accessing incorrect or malicious websites. DNS servers act as a directory that translates domain names into IP addresses, similar to a phone book. When a user enters a website address, the browser queries the DNS server for the corresponding IP address and then connects to the target website using that IP address. If the domain name-to-IP address mapping on the DNS server is tampered with, users will be directed to incorrect or malicious websites.

③ URL Filtering

This method involves examining the URL (Uniform Resource Locator) requested by the user to prevent access to specific pages or content. A URL is a unique address for each page or content on the internet, similar to a postal code. When a user enters a URL, the browser sends a request to the target website, asking for the corresponding page or content to be returned. If the requested URL is filtered, the user will be unable to access that page or content.

④ Keyword Filtering

This method involves checking whether certain specific words are present in the user's request or in the returned page or content to prevent access to particular pages or content. Keywords refer to words with specific meanings or sensitivities, similar to taboo words. When a user enters a URL, the browser sends a request to the target website, asking for the corresponding page or content to be returned. If certain keywords are detected in the user's request or in the returned page or content, the user will be unable to access that page or content.

Using VPN to Bypass Website Blocking

A VPN (Virtual Private Network) is a service that allows users to bypass website blocking by encrypting network traffic and changing IP addresses, enabling access to any desired website. The working principle of a VPN is as follows:

① Encrypting Network Traffic

When a user uses a VPN, the VPN encrypts the user's network traffic, making it unreadable and unmodifiable by others. This allows the user to avoid website blocking through URL filtering or keyword filtering.

② Changing IP Address

When a user uses a VPN, the VPN hides the user's real IP address and assigns a new IP address to the user. This allows the user to avoid website blocking through IP address blocking or DNS spoofing. Additionally, by selecting different VPN servers, users can change their IP address to appear as if they are in a different country or region, thus accessing websites restricted due to geographical location.
