It’s estimated that over 1.7 billion websites exist, but this number fluctuates daily, as websites are launched or lost. Despite the ebb and flow, the Web is massive and 4.5 billion people across the world contribute with online interactions.

Just over 30 years since it was born, the World Wide Web has completely transformed our lives. With a few clicks of your mouse or a simple voice command, you can have essentials delivered straight to your door or connect with a friend all the way across the globe. 

Have you wondered what makes up the complex infrastructure of the Internet or interconnected World Wide Web? What sites dominate our online searches? And, just how vast is the network that we use and rely on daily for information?  

To attempt to answer these insurmountable questions, we’ve compiled everything to know about what makes up the Internet and Web and why this information matters for you and users around the world as these systems grow.

How Big is the Internet?

Even for complex data analysts, it’s difficult to get an accurate picture or truly understand how big the Internet and World Wide Web is. 

Beyond the ever-changing “surface” web is the unquantifiable dark web or invisible web. The dark web is estimated to be a thousands times larger than the surface web, and each is growing by the day. Just think: in the minutes it takes you to read this, hundreds to thousands of new sites may be born.  

We use the Internet in real-time now more than ever, whether it’s with streaming content or video calls. Meaning, the networks we use have become more aware of how to operate, deliver, and prioritize information than ever before. 

Will we ever reach full capacity? While the answer is impossible to predict, there are ways to attempt to quantify how big the Internet is with the questions below.

How Much Data
is on The Internet?

To estimate the size of the Internet, we can evaluate how much data there is in the world. Cisco’s Visual Networking Index states that the annual global IP traffic will reach 4,800 zettabytes (ZB) per year by the year 2022. 

TechTerms defines a zettabyte as “1021 or 1,000,000,000,000,000,000,000 bytes.” On a grander scale, one zettabyte is “approximately equal to a thousand exabytes, a billion terabytes, or a trillion gigabytes.”  

If you compare how many terabytes are in a zettabyte, you can get a picture of just how large a zettabyte is and in turn, the size of the Internet. A Cisco analyst calculated that “if each terabyte in a zettabyte were a kilometer, it would be equivalent to 1,300 round trips to the moon and back.”

How Many Web Pages Exist?

According to statistical research by WorldWideWebSize, the web contains over 6 billion indexed web pages as of 2020. This accounts for all pages, whether active or inactive.

Web page vs. website

A web page is any single page on the Internet that can include a range of content from video to text, while a website is a collection of web pages under one domain. 

Let’s consider an example. Nike is one of your favorite brands to shop online, but the women’s running shoes product page is the page you frequent the most. The Nike site as a whole is the website, while women’s running shoes is one of the web pages that makes it up.

How Many People Use the Internet?

InternetLiveStats estimates that over 4 billion people search the web every day. That’s over half of the global population. This estimation in itself is telling of how massive the Internet is, since from your computer at home, you can browse and peruse sites endlessly.

Facts About the Internet

How much do you really know about what powers our digital world? The Internet and Web have truly revolutionized how we connect with each other. Let’s take it back to the beginning and define some of the most important milestones and terms to know. 

World Wide Web vs. Internet

While the Web and Internet are intricately connected and many people use the terms interchangeably, they are actually two different things. 

Think of the Internet as a network consisting of infrastructure and technologies that you use to connect whether it’s at your office, home, or a coffee shop.  

The World Wide Web (or Web) is the system that enables the exchange of information over the Internet through HTTP, essentially what powers the technology.

When Was the Internet Created?

The Internet was created in 1989 by Tim Berners-Lee, who’s now considered the inventor or “Father” of the Internet. He now leads the W3C which is the organization that oversees the development of the World Wide Web.

How Was the Internet Created?

Berners-Lee developed hypertext, the method of instant cross-referencing that supports communications on the Web, making it easy to link content on one web page to content located elsewhere. The introduction of hypertext revolutionized the way people used the internet. With that, he introduced the first browser and editor, as well as HTTP/HTML protocols. 

What Was the First Website?

The very first website was and went live in 1991 to provide information on the World Wide Web Project led by Berners-Lee.

Did you know the first website is still live today? You can check it out here:

How Many Websites are Created Everyday?

While there is no final or concrete answer, Mill For Business estimates that if “every 24 hours we get 547,200 increase in the total number of websites worldwide,” there are “over 380 websites are created every minute”.

Number of Active Websites

While over 1.7 billion websites exist, less than 200 million of those websites are active. Websites become inactive for a number of reasons ranging from technical issues, server problems, or late and unpaid registrar payments.

How Many Domains are There?

Verisign reported 362.3 million registered domain names as of the fourth quarter of 2019. This number has grown 3.9 percent year over year, with .com domains topping the list as the most widely used. 

Types of Domains

Every domain name operates under a Domain Name System (DNS), which directs visitors to your website by translating the name into its related IP address and locating where the resource is stored. 

Top level domains (or TLDs) are at the highest level in the DNS structure of the Internet. Check out the very first TLDs to be introduced and which are most commonly used today.

Types of Websites

Websites are separated into two different types: static and dynamic. 

static website

Static Websites

A static website is the most basic and easiest type of website to create. It’s made up of pages that have fixed content coded in HTML. It displays the same information to its site visitors. 

Unlike dynamic websites, static websites don’t require programming or database design. A static site can be built by simply creating a few HTML pages and publishing them to a server.

Static sites have:

  • No users or comments
  • No interactivity

Dynamic Websites

Dynamic websites contain web pages that access information from a database and are generated in real-time. Compared to static websites, a dynamic site is more functional. 

These pages include Web scripting code, such as PHP or ASP. When a dynamic page is accessed, the code within the page is parsed on the Web server and the resulting HTML is sent to the client’s Web browser. 

Most content management systems (CMS) run on systems such as WordPress can create a dynamic site. Dynamic sites are helpful for large sites that may have hundreds to pages to manage, since different users can update content without editing the layout of the pages. 

Common examples include:

  • E-commerce sites
  • Blogs

What will the next decade hold and how will it change our lives? Wired stated, “At its core, if the 2010s have been all about software,” then the “2020s might be the moment when infrastructure reclaims centre-stage.” The Cisco EVP and GM David Goeckeler stated it best, “The key promise of the Internet of the future is that no one gets left behind this time.”
