What is a domain?

28-06-2023 - Blogs

An integral part of our online experience

Domains are essential to our online experience and have evolved to become an integral part of our modern digital world. In 1980, the concept of “domain” was unknown, but in the year 2023, it is almost impossible to avoid encountering the need to use a domain name, regardless of whether you are sitting in front of a computer, with your mobile phone in your hands or a tablet on you lap.

What is a domain?

In its basic form, it is a unique text-based identification of a website or a so-called URL. This is what we usually type in a web browser to visit a specific page, e.g. “https://thedomainrobot.com/” or “https://google.com“. They thus function as human-readable substitutes for the complex numerical IP addresses that the Internet uses to identify servers and their location. If you enter, for example, “https://google.com” in your browser, there are actually several things behind the scenes to deliver the desired web page.

So when you try to access your favorite web shop via your browser, your computer sends a query to a so-called DNS server (Domain Name System), this DNS server is then responsible for translating the entered domain names into IP addresses for the corresponding IP address, e.g. might “https://google.com” become “”. So there is not a computer somewhere in the world with a sticker that says “https://google.com“, the computer has instead been assigned an IP address.

In many ways, a domain name is the same to an IP address – as a private address is to a set of coordinates (lat/lng) on ​​a globe. Roughly speaking, a domain name acts as a convenient tool that allows us humans to find and access websites without having to remember complex numeric IP addresses for each website.

And now you may be wondering about how a URL is translated into an IP address – that is a slightly longer explanation, which we certainly don’t want to cheat you on – that’s why this topic will gets its very own blog post!.

What is a website address?

A website address, also known as a URL (Uniform Resource Locator) is a combination of different elements that give your browser specific information about how it should communicate with the server where the page is located – and the domain is one of these elements.

1) The protocol

HTTP/HTTPS indicates the protocol used for communication between your browser and the server where the website is located. For many years HTTP (Hypertext Transfer Protocol) was the most common protocol used on the Internet. However, due to vulnerabilities to hacker attacks and protection of user privacy, HTTPS (Hypertext Transfer Protocol Secure) has now become the standard protocol.

2) The subdomain

www is an example of a subdomain and is traditionally used as an abbreviation for “World Wide Web”. It became common to use www as a default prefix when the internet was a whole new thing, but it’s not really used anymore – but it will usually be a good idea to still set it up on your DNS configuration, because there are a small number of people who still writes www in front of everything.

A subdomain is a way of organizing and structuring websites on the Internet. It can be compared to the organization of folders on a computer, where files and resources are grouped by categories.

Good examples in addition to www could be “app.domain.com”, “test.domain.com” or “mail.domain.com”. These can be customized as needed and can contain letters and numbers to create unique identifiers. They therefore provide the opportunity to divide a page into different sections and/or offer specific functionality under different addresses.

3) Second-level domain (SLD)

A second-level domain is the name that you have registered or bought/own/rent. This is the part that comes before the TLD

4) Top-level domain (TLD)

A top-level domain (TLD) is the last part of the URL that indicates the overall category or country affiliation. The TLD is usually a two- or three-letter abbreviation found after the last period of the full URL/website address.

The TLD can have different purposes and meanings. It can, for example, used to indicate the language of the page, the country of affiliation, the type of organization, or perhaps the industry that the page represents. Here are some examples of common TLDs and their purpose:

  • .com (Commercial): Generally used by commercial companies and has a global reach.
  • .dk, .se, .com (country-coded TLDs): These indicate countries, e.g. .dk for Denmark and .se for Sweden.
  • .org (organization): Often used by non-profit organizations and interest groups.
  • .net (network): Historically used by network-related businesses and organizations.
  • .edu (education): Reserved for academic institutions and education-related organizations.
  • .gov (government): Exclusively for government agencies and government organizations.

The TLD can e.g. give an indication of language, geographical location or the purpose of the page, but it is important to note that it is not always an absolute indicator. Many sites use generic TLDs like .com despite language and geographic “location”.

5) Page or file name

The name of the file/page in question has on the server

6) Filetype

The file type of the page – such as .html, .aspx, php, .zip, .txt..

How Do Domain Names Work?

For a clear comprehension of how domain names work, we will explore the process that occurs when you type it into your web browser.

When you enter a domain name into your web browser, the first action taken is a request sent to a worldwide network of servers forming the Domain Name System (DNS). Next, these servers search for the name servers or DNS servers associated with the domain, and they send the request to them. For instance, if your website is hosted on Bluehost, the DNS records of your name server info might resemble this:


These name servers are computers operated by your hosting firm. The computer where your website is located will be connected to by your hosting provider. This server, known as a web server, has special software installed on it (Apache and Nginx are two popular types of web server software). The web server will then retrieve the webpage and any related data and ultimately, this information is returned to the user’s browser.

Web hosting, Domain name, Website

How is Domain Name Different from a Website and Web Hosting?

A website forms the online identity of your business and consists of numerous files like HTML pages, pictures, and web builder software. Think of your domain name as your website’s address, while web hosting is akin to the home in which your website resides. The physical computer where your website’s files get stored is known as the server, provided as a service by hosting agencies.

To establish your website, you require both web hosting and a domain name. These are essential components whether you’re constructing a personal blog, a small business site, or an eCommerce platform. However, it’s crucial to note that they are distinct things, and you have the option of purchasing them from two different providers. But we suggest obtaining your web hosting and domain name from the same provider for ease of management, is the best way, for most people.

Who is Responsible for the Domain Name System?

The Domain Name System, often summarized as DNS, is akin to the “phonebook” of the online world. Whereas searching for sites using numerical IP addresses is laborious, DNS delivers the benefit of utilizing easy-to-retain domain names.

Different organizations worldwide bear the responsibility for administering the DNS. These authoritative entities ensure that this crucial virtual directory is appropriately regulated, coordinated, and maintained. They handle coding and regulations to map domain names to corresponding IP addresses and keep the virtual world running seamlessly.

At the helm of these important tasks is the Internet Corporation for Assigned Names and Numbers or ICANN. ICANN, a non-profit entity, coordinates and keeps the DNS running efficiently. It also ensures that every internet address is distinct, averting potential mix-ups.

Below ICANN, there’s a hierarchy of companies and organizations that deal with different domain levels. Take for example registries; they take care of top-level domains (TLDs) like .com, .net or .org. Then, there are registrars, beneath registries. They interact directly with the public, offering domain name registration services.

Lastly, we have web hosting companies and internet service providers (ISPs). They play a role in DNS workings by storing DNS data in their servers and providing internet connection services respectively.

In conclusion, the responsibility for the Domain Name System is decentralized. It’s a task shared by ICANN, registries, registrars, web hosting companies and ISPs in pursuit of providing a convenient internet experience.

6) Expired/Deleted Domains

Another possibility is to look for expired/deleted domains, here you can, without having to make demands on your own creative abilities, be lucky to find names that have been in use before, but are now available. In addition to easing the need for creative expression, there are also a lot of other advantages of expired/deleted domains.

How to buy a Domain Name / Website

Acquiring a domain name may seem like a daunting task, but it’s actually a straightforward process.

1) Find a domain name that suits your new Website

Before you do anything else, you should brainstorm your desired domain name. This is an important task as your domain name effectively acts as your brand, and for many also the hardest task, when creating a new website.

2) Check if your domain name is available

After you have a list of potential names, you need to check if the name is available. All domain registrar provides an easy to use search bar to see if a domain name is available – as an alternative, you can also use our Domain Name Analyzing-tool to see if a domain name is available.

3) Pick a domain registrar

There are countless providers out there – from GoDaddy.com, Doman.com, and Namecheap.com, to more boutique options. Each will provide prices, so shop around to see which one suits your needs the most. In reality it doesn’t really matter much with domain registrar you pick – if you are choosing to use one of the more established domain registrars – in the end most of them have VERY similar prices and support.

4) Pick your hosting package and add-ons (Optional)

If you are choosing to have your website hosted the same place that you register your domain name – you now need to figure out what kind of web hosting you want. Most providers, offer a range of different packages – packages suited for websites with a couple of daily users to packages suited for websites with thousand of daily users. A good rule of thumb is that, unless you have an already established website or a well known brand – you most likely will be fine with a starter web hosting package.

During the checkout process, you’ll also be offered additional services like email accounts, privacy protection, and similar. Choose the ones which resonate with your needs.

5) Provide Contact information

Next you’ll be most likely be required to provide detailed contact information for the WHOIS database. For domain privacy, consider using the privacy or proxy services often provided by registrars. If you choose NOT to pay for domain privacy, your contact information will be available to the public – and you will most likely end up getting spammed – so we would strongly suggest that you consider choosing to opt in, for the domain privacy add-on!.

5) Pay

Lastly, make your payment to secure your domain name. If you don’t accidentally want to loose your domain name, you might wanna consider to opt-in for auto-renew

Frequently Asked Questions About Domain Names & Websites

What is a subdomain?

A subdomain is essentially a child domain that resides under the main domain. For instance, a subdomain for website.com could be shop.website.com. Also regarded as third-level domain names, subdomains are quite common. After registering a domain, it is within your purview to create as many subdomains as you wish.

Many websites employ subdomains to set up separate sites under the main domain name. As an example, a commercial website may establish a subdomain for their blog or their ecommerce store, as seen in blog.domain.com or shop.domain.com.

Is it possible to cancel my domain name registration?

Any string that comes prior your main domain and is ensued by a dot, like tutorial.wpbeginner.com, is deemed a subdomain. This does not detract from the accessibility of your website, with or without the ‘www’, as long as your domain is configured correctly. Therefore, the necessity of www in a website’s domain name has become a matter of personal preference rather than a compulsory requirement.
