The dream of the internet’s creation was a world without borders, where information flowed freely and everyone could connect and access knowledge. This ideal, unfortunately, hasn’t fully come to pass. In some countries, the internet isn’t quite so free. Governments may censor websites to control the flow of information, driven by a desire to uphold their values or exert control. This article delves into the intricate issue of internet censorship: what it is, its methods, and, crucially, what we can do about it.
What Is Internet Censorship?
Internet censorship restricts or blocks access to specific online content. This blocked content becomes practically off-limits and potentially illegal to view or obtain within the censor’s control. In some cases, even publishing this restricted material can be a punishable offense.
What’s Blocked

Censorship has the potential to impact various forms of internet content, but typically, the following categories are among the most commonly targeted:
- Pornography
- Torrenting
- Social media
- News media
- Foreign websites
Where Censorship Happens
Internet censorship isn’t limited to governments like China’s Great Firewall restricting foreign access. It can also be implemented at various levels:
- Home: Many parents utilize tools like blacklists and keyword filters to manage their children’s online safety by restricting access to inappropriate content.
- Workplace: To maintain productivity and limit distractions, businesses often implement firewalls to block specific websites or categories of websites.
- Internet Service Providers (ISPs): ISPs have the technical capability to block access to certain websites. However, debates like Net Neutrality address concerns that ISPs might prioritize certain content or throttle bandwidth, creating a form of indirect censorship.
How Does Internet Censorship Work?
Similar to the versatility of serving eggs in various ways, internet censorship employs diverse methods, but it typically maintains a cold demeanor.
DNS Tampering
Hackers may utilize DNS tampering to manipulate DNS records, gaining unauthorized access to networks, which could lead to malware infiltration or identity theft.
Blocking of IP Addresses
Internet censorship often involves blocking specific IP addresses, the numerical codes directing computers to websites. This blocking can occur on an ad-hoc basis or through regional restrictions known as geo-blocking.
Filtering Keywords
Keyword filters, commonly used in parental controls, automatically or manually block specific words to restrict access to certain content. This method is also employed on a larger scale in countries seeking to suppress information.
Filtering Packets
Some firewalls make filtering decisions based on protocols, ports, network addresses, and source/destination IP addresses, rather than domain names or keywords. This method grants access solely based on IP addresses, bypassing traditional antivirus-based filtering.
Traffic Shaping
Traffic shaping, or packet shaping, manages bandwidth to prioritize certain applications over others. This practice may throttle or slow down non-prioritized apps, effectively nudging users towards preferred services or applications, potentially influencing their internet usage habits.
Port Number Blacklisting
Port number blacklisting involves ISPs blocking traffic based solely on transport protocol and port number, disregarding IP addresses. This method allows for the blocking of entire applications, rather than specific websites.
Internet Censorship Around The World
To draw a parallel, internet censorship varies significantly across different countries. Freedom House, a nonprofit organization dedicated to promoting media freedom and freedom of expression, annually ranks countries based on their levels of internet censorship. Thus, we present their compilation of the best and worst countries for internet censorship.
Countries with Little to No Censorship
- Canada: Known for its open society, Canada enforces minimal restrictions on online content, regardless of religious, political, or social media nature.
- Iceland: Iceland enjoys widespread internet access and boasts strong legal protections for freedom of expression, even for those exposing sensitive information.
Countries with Strict Censorship
- China: China enforces a robust internet filtering system that restricts access to foreign online platforms and heavily monitors incoming traffic. This system limits the information available to citizens and restricts discussions on sensitive topics.
- Russia: Recent events have intensified internet censorship efforts in Russia. The country already restricts access to numerous foreign websites, and proposals for a further isolated online environment could significantly limit internet freedom. Additionally, Russia restricts tools like VPNs that can circumvent censorship measures.
How To Avoid Internet Censorship
Whether you’re facing censorship at home, work, from your ISP, or your country, there are several solutions available to enhance your online freedom. Some options are free, while others require payment, but all can be set up quickly and effectively increase your protection against censorship.
VPNs (Virtual Private Networks)
VPNs encrypt your visited websites and device IP addresses, effectively bypassing website restrictions by concealing your web activity in a secure tunnel.
Secure Browser (e.g., Tor)
Secure browsers like Tor operate similarly to VPNs by hiding your IP address and clearing cookies upon closing website tabs. They encrypt your activity threefold, ensuring security even after visiting restricted websites.
Avoid Using Incognito Mode
Contrary to popular belief, Incognito Mode doesn’t completely erase your web history. While data is deleted locally, your ISP can still track your online activities unless you’re using additional security measures like a VPN. While Incognito Mode can conceal web activity from others sharing your device, it’s insufficient for privacy from your ISP.
Proxy Servers
Proxy servers, like VPNs, hide IP addresses to provide more online freedom. However, proxies lack the comprehensive protection offered by VPNs, as they only conceal your IP address without encrypting your data.
FAQ’s
What exactly is internet censorship?
Internet censorship refers to the deliberate blocking or suppression of specific online content. This blocked content becomes difficult or illegal to access within the jurisdiction of the censoring entity.
What types of content are typically targeted for censorship?
Commonly targeted content includes pornography, torrenting, social media platforms, news media websites, and foreign websites.
Where does internet censorship occur?
Internet censorship can happen at various levels, including at home, in the workplace, and by Internet Service Providers (ISPs), apart from government-imposed restrictions as seen in countries like China.
How does internet censorship work?
Internet censorship utilizes various methods such as DNS tampering, blocking of IP addresses, filtering keywords, traffic shaping, and port number blacklisting, to control or restrict access to certain online content.
How does internet censorship vary around the world?
Internet censorship varies greatly across different countries. Some countries, like Canada and Iceland, impose minimal restrictions on online content, while others, like China and Russia, enforce strict controls over internet access and content.
What can individuals do to bypass internet censorship?
Individuals can utilize tools like Virtual Private Networks (VPNs), secure browsers like Tor, or proxy servers to enhance their online privacy and bypass censorship imposed by governments, ISPs, or other entities. These tools encrypt internet traffic and hide IP addresses, providing greater online freedom and privacy.
Conclusion
Internet censorship presents a significant barrier to the free flow of information online. While some countries embrace freedom of expression, others impose strict controls. Despite these challenges, individuals can use available tools to bypass censorship and protect their online privacy. Moving forward, it’s crucial to advocate for a more open and unrestricted internet, fostering global connectivity and freedom of expression.
