Who Controls the Internet? How the Internet Works: An In-Depth Guide

The internet is a cornerstone of modern life, driving communication, business, and entertainment globally. But have you ever wondered who controls the internet or how it works? Understanding the intricate network that forms the internet is essential, as it is a powerful tool for maintaining freedom and democracy worldwide. Let’s delve into this fascinating topic.

Who Controls the Internet?

Contrary to popular belief, no single entity, government, or corporation controls the internet. Instead, it operates as a decentralized system. Here’s how it functions:

1. ICANN: The Top-Level Authority
   The Internet Corporation for Assigned Names and Numbers (ICANN) is a nonprofit organization based in Los Angeles. ICANN oversees domain names, ensuring that the internet remains a decentralized network. It grants authorization to companies like GoDaddy to sell domain names and manages top-level domains (TLDs) like .com, .org, and .gov. Visit ICANN’s website for more details.
2. Internet Service Providers (ISPs)
   ISPs such as Jio, Airtel, and BSNL play a critical role in delivering internet connectivity to homes and businesses. They provide the necessary infrastructure and can block or throttle access to certain websites if directed by government regulations. However, their power is limited as users can bypass restrictions using tools like VPNs or public DNS servers.
3. Global Infrastructure: Underwater Cables
   Massive underwater cables connect continents, forming the backbone of the internet. These cables are laid by companies with significant power in enabling global connectivity.
4. Decentralized Networks
   The internet is essentially a network of networks. Millions of servers, data centers, and user devices contribute to its existence, ensuring no single point of failure or control.

How the Internet Works

The internet connects billions of devices worldwide through servers, IP addresses, and domain names. Let’s break it down step-by-step:

1. IP Addresses and Domain Names
   Every device and website on the internet has a unique IP address, a numerical identifier. Since IP addresses are hard to remember, they are mapped to human-readable domain names, like www.google.com.
2. Domain Name Servers (DNS)
   The DNS acts as a translator between domain names and IP addresses. When you type a URL in your browser, the DNS resolves it to the corresponding IP address. Sometimes, ISPs block access to specific DNS entries, but this can be bypassed by switching to public DNS servers, such as Google’s DNS 8.8.8.8.
3. Servers and Hosting
   Websites are stored on servers, which are powerful computers running 24/7. These servers can be owned personally or rented from hosting providers like Amazon Web Services (AWS) or Bluehost.
4. Data Flow and Access
   Data travels through physical cables and wireless connections (e.g., mobile towers for 4G/5G networks). Your device connects to the nearest access point, sending requests to servers and receiving data in return.

Building Your Own Website

Creating your own website gives you a small piece of the internet. Here’s how to get started:

1. Buy a Domain Name
   Use domain registrars like GoDaddy or Namecheap to purchase a unique domain name.
2. Choose a Hosting Provider
   Opt for a hosting service to store your website. Reliable options include Bluehost and HostGator.
3. Link Your Domain to Hosting
   After purchasing hosting, link your domain name to the hosting server and configure the DNS settings.
4. Publish Your Content
   Design your website using platforms like WordPress or custom code. Once done, publish it to make it accessible worldwide.

Protecting Internet Freedom

While the internet is decentralized, some governments attempt to control it through censorship. Countries like China block major websites like Google, YouTube, and Facebook. However, tools like VPNs and alternative DNS servers empower users to bypass restrictions and maintain access to information.

Final Thoughts

The internet belongs to no one yet everyone. Its decentralized structure ensures resilience and freedom. By understanding how the internet works, you can leverage its power responsibly, whether by building your own website or safeguarding your online freedom.
