You’re here because you want to know what a domain name is, and how domains work? It seems like an easy enough question to answer, but it can still trip up a lot of beginners.

When you’re building your first website there are a lot of technical terms you’ll come across. And there are a handful of things you’ll need to get right if you want your website to not only work properly but thrive and grow.

It’s easy to confuse a website with a domain name, your hosting provider, or even understand what does domain mean?

Below you’ll learn everything you need to know about a domain name, how they function, and why they’re necessary.

What Is a Domain Name?

A domain name is what you type into a web browser to access a website. The domain definition is a unique name that identifies a website. Chances are you’ve already typed in a few domain names today.

For example, the domain name of Twitter is While the domain name for this website is

Domain names are completely unique to a website, which is why they are so valuable.

Domain Names and IP Addresses

When we look at the internet as a whole it’s essentially a network of computers connected to each other. Each of these computers is assigned a unique IP address that identifies that computer alone. IP addresses resemble a random string of numbers, which look like 67.454.66.3.

But, could you imagine having to remember that unique string whenever you wanted to visit a website?

It would be a pretty frustrating experience.

So, instead, we have domain names that stand in place of these unique IP addresses. For example, we can look at an IP address as the GPS coordinates of your home, while your domain name could be your street address, or even the more informal name, “Jim’s House”.

They all reference the same thing, but some methods are easier to remember.

How Do Domain Names Work?

Now that you’re equipped with the basics of domain names and IP addresses, let’s dive a little deeper into how they actually work. This will give you a deeper background on what happens behind the scenes when you type a domain into your browser.

Once a domain name gets typed into a browser that request gets sent out to a network of servers known as the Domain Names System (DNS). This network then looks up the nameservers of that domain and forwards the request to the appropriate server.

The nameservers are managed by your hosting company, which will then forward the request to the specific server where your website is stored.

The server then locates the website, or web page, that was requested and sends the data back to the user’s browser.

That’s a lot! Right? All of this happens in under a second. This request occurs so quickly, you don’t even notice it’s happening.

Different Types of Domain Names

When you’re trying to find the perfect domain name you’ll be able to choose between dozens of different domain name extensions. These are the final part of the domain name, for example, .com, .net, and .org.

Here are the most common types of domain names you’ll come across: 

1. Generic Top-level Domains

Top-level domains are the most popular types of domain names. There are hundreds of these available and will generally be the best type of extension for your domain.

Here are some of the most common:

  • .com (commercial)
  • .net (network)
  • .org (organization)

Ideally, you’ll choose a domain that uses one of the above extensions. However, there are hundreds of these available. The entire list of available TLDs can be found on the IANA website. Keep in mind that not every TLD on the list will be available for you to register.

2. Country Code Top-Level Domains

Country code TLDs are assigned to specific countries and generally used for websites that are based (or serving an audience) in those countries.

However, some ccTLDs are used in other circumstances as well. For example, the ccTLD .co is for the country Colombia. But, you’ll find a ton of new websites and startups use that domain as well.

Here are some common ccTLDs:

  • .us (United States)
  • (United Kingdom)
  • .ca (Canada)
  • .de (Germany)
  • .fr (France)

3. Sponsored Top-Level Domains

rTLDs are a group of top-level domains that are reserved for specific organizations and agencies. To register one of these you’ll need to meet the specific requirements. If you operate under the category that each domain is reserved for, then you can use that TLD.

Otherwise, pick one from one of the other categories. 

Here are a few examples:

  • .gov (these are reserved for government organizations)
  • .mil (these are reserved for military operations)
  • .edu (these are reserved for educational institutions)
  • .int (these are reserved for international organizations)

Domain Names vs Websites

Domain names and websites are related, however, they aren’t the same thing. For example, let’s look at your phone number and existing phone. Although you need both working together, they aren’t the same.

Your phone number is like your domain name, while your website will be whatever phone you’re currently using.

You can get a new phone (website), but you’ll keep your existing number (domain name) no matter if you upgrade your phone, or even move to a new provider.

Let’s look at another example:

Say you’re running a website that offers running tips and your current domain name is “”. However, you found a new domain that’s even a better fit, so you buy it. All you have to do is connect your new domain to your existing website and everything will be the same, except your domain.

Your domain name is never stuck with any website. You can disconnect it and use it for another website, or purchase a new domain and connect it to your current site.

Understanding the DNS System

The Domain Name System (DNS) is managed by an organization named Internet Corporation for Assigned Names and Numbers (ICANN). They’re a non-profit that creates policies and manages the existing domain name system.

Any registrar that sells domains must get permission from ICANN to conduct business.

Domain name registrars (like the one here at HostGator) can sell domains, and help you manage your records, renew your domains, conduct domain transfers and more.

Choosing the Right Domain Name for Your Website

There’s a lot that goes into finding the perfect domain name for your new website. It needs to convey what your website is about in a few characters, it needs to be brandable, memorable, and a lot more.

Your domain is responsible for creating a first impression, it can impact your SEO, and needs to be in alignment with your brand. It’s also important to consider the domain meaning, you’ll want to ensure the meaning of the words is in alignment with your brand, and doesn’t have an alternative meaning in other languages. That’s a lot for a few simple words!

Luckily, we’ve written an entire article on finding the right domain for your needs.

It depends on the registrar you used to register your domain, some allow you to cancel whenever, while with others you’ll have to wait for your domain name to expire.
