What is a Domain Name?

The domain name is an address that we type in the browser search bar to visit a website. It is a unique name for a website.

For example, if you want to visit Facebook then you will type facebook.com inside your web browser. This will take you to the Facebook website.

Here, facebook.com is the domain name of this website.

Usually, each domain name consists of two main sections i.e. Website’s name (facebook) and domain name extension (.com).

The internet is a giant network that connects a huge number of computers, mobiles, and other electric devices together.

Now the question is how this network identifies those devices separately.

In more simple words, when you search for any website how does the internet understand which computer or device you are trying to connect to.

To solve this issue, the internet uses a system called DNS (Domain Name System).

What is Domain Name System (DNS)?

DNS (Domain Name System) is basically a database or collection of all domain names with their corresponding IP numbers.

Every device connected to this giant network has a unique number; this number is called an IP address.

How domain name system (DNS) works

Therefore, when you are searching with a domain name, you are trying to connect to a specific IP address. Every domain represents a specific IP.

For example, if you type google.com that means you are typing this “” IP address. You can also use an IP number instead of that domain.

So, when you enter a domain name in your browser, it looks into the DNS server to find out the IP for that domain.

When your browser finds the address then it can connect to the server or computer where that website is being hosted.

If the IP address of your website domain changes then DNS automatically updates itself with the new address.

Why Do We Use Domain Name Instead of IP?

The simple answer is that domain names are much easier to remember and use than IP addresses.

IP is a set of numbers that is hard to remember. The human brain can easily memorize a name than a number.

There are a large number of websites that we visit in our daily life. It would be very difficult to memorize all the IP addresses.

That is why domain names were introduced to make this process simple.

Now we can easily remember website names and visit. You don’t need to care about those long numbers (IP).

Free VS Paid Domain Names

You can easily collect free domains or names from different website builders for your website such as Blogger, Wrodpress.com, Squarespace, Wix, Weebly, etc.

More specifically, these website builders give you a “sub-domain” of their website. If you don’t know what a sub-domain is don’t worry, we will discuss it in the later section.

In short, a sub-domain is an additional section of the main domain name. Sub-domains usually look something like this:

  • example.wix.com
  • example.weebly.com
  • example.wordpress.com

A free sub-domain is not always convenient for your website if you are considering long-term business and trying to build a unique brand.

Because you don’t have full control over the free sub-domain provided by website builders.

In this case, you have to purchase a domain name for your website. You will have a full section dedicated to how to choose a perfect domain name and how can you buy it.

How Does Domain Name Actually Work?

You already know all the basics to understand how a domain name works when you type it in your browser.

When you enter a website name in your web browser, it first sends a request to a global network of servers that creates the Domain Name System (DNS).

DNS contains all the names and IP addresses. These servers then look up the IP address associated with the name you have entered in your browser.

When the browser receives the actual IP address from DNS, it connects with the name servers by following the number address.

For example, if you are using Namecheap as your hosting provider, then the name servers will be like this:

  • dns1.namecheaphosting.com
  • dns2.namecheaphosting.com

These name servers are the computers maintained by the hosting company. Then these computers will forward your request to the specific computer where your desired website is stored.

The computer where the website is stored is called a web server. Now web server will process the request for webpage and information.

Finally, the web server then sends the webpage and information back to your browser. This is how a domain name works behind the scenes when we browse websites.

Different Types of Domain Names

Different types of domain names. Showing different types of domain extensions

A domain name contains two main sections one is a website name and another one is an extension. Website domains are available with different extensions.

Most popular one is .com extension among all extensions. There are many other options, you can use like .org, .net, .info, .edu, .gov, and more.

Top-Level Domain – TLD

Top-level domains or TLDs are generic domain extensions that have the highest position in the Domain Name System (DNS).

The domains that include .com, .org, .net extensions, are in this category.

There are many other TLDs but they are less popular. We don’t recommend using them for your website.

For example, .biz, .club, .tv, .info, .name, and many more.

Second Level Domain - SLD

According to Wikipedia, a second-level domain (SLD) is a domain that is directly below a top-level domain (TLD).

For example, in webmound.com, webmound is the second-level domain

SLDs are the name of a business that registered the domain name with a registrar. The brand name or company name is the indicator for potential customers.

Country Code Top Level Domain – ccTLD

Country-specific domain names with country code extensions are called Country-code top-level domain or ccTLD.

For example, .au defines Australia .uk defines the United Kingdom, .de defines Germany, .ca defines Canada etc.

You can use a domain name with those extensions to target audiences in a specific country.

If you have a website with a .uk extension that means your website is strongly associated with The United Kingdom.

Sponsored top-level domain or sTLD is a category of TLDs according to ICANN. These sTLDs are proposed and sponsored by specific communities or private organizations.

For example, .edu for education-related organizations, .gov for different government sectors, .mil for military-related websites, and more.

Differences Between a Domain Name and a URL

The structure of a URL and showing different parts of a URL

Some people get confused between a domain name and a URL (Universal Resource Locator). They have some similarities but these two do not indicate the same thing.

A URL is a complete address that points toward a specific page on a website. On the other hand, a domain name represents the entire website.

The domain name is a part of a URL. It shows which website this URL belongs to.

A URL has a few different parts. It has a protocol, a domain name, and a unique path. This unique path represents a specific page of that website.

Difference Between Domain Name and Web Hosting

As a beginner, many people get confused about this domain name and web hosting. They are separate services but have a connection to run a website.

The domain name is the web address of your website and web hosting is the actual home where your website lives.

A website is made up of different files like HTML, CSS, JavaScript, Images, etc. A web hosting is a computer where all these files are stored.

Such computers are known as servers and they are provided and maintained by hosting companies.

Though domain and hosting are separate services, you can buy them from the same company or different companies.

How it will work if you buy them from separate companies?

Every hosting company has specific name servers. You can connect your domain name and web hosting by using name servers.

You need to update domain name settings by entering Name Server information provided by the hosting company.
