What is a Domain Extension

A domain extension is a section at the end of a webpage address that indicates the country or region of a website. Domain extensions provide a mapping of website domain names to their geographic location. For example, if you visit the website, the domain extension is .com. There are many variations of this convention in different countries and regions. Many of these variations help to provide ubiquitous access to websites.

You’ve got an idea, a business plan, and a design. Now what? As you move through the process of registering your domain, it can be tough to know which terms and extensions you should choose. With so many available options, what is the best way to make your choice?

What is a Domain Extension

As you research for your perfect domain name, it may seem like choosing a domain extension is as complicated as it gets. But before you go nuts trying to wrestle which one goes where let’s simplify this process. The truth is that websites often use more than one extension at once. So let’s figure out what are the types of domain extensions, and you can choose the best one.

Types of Domain Extensions

For most purposes, a domain extension is nothing more than a placeholder that’s used to uniquely identify a website. It’s just a URL extension used in web addresses. But, as you’ll soon learn, a domain extension can be a lot more than that. First, let’s clear out on the domain name extension definition.

A domain extension is a domain name extension that registered by an administrative entity on behalf of the domain name holder. These types of extensions modify the name of the original domain to “”. In the top-level domain hierarchy, these are under “.com” and followed by other extensions such as “.net” or “.org”. We’ll call these “Parent TLDs.” For a business, the most often considered type is the “.com.”

When brands launch new websites, they can resort to cloud server hosting services and choose an extension for the domain. This is to identify the role the site plays. For example, companies might choose the main website with a main category followed by other subdomains which have varying categories. Below is a list of the common types of domain name extensions explained.

Generic Domain Extensions

Generic domain extensions, .net, and .org. Google appears to be largely targeting domains related to generic domain extensions rather than individual websites’ domain names. As of today, the number of available TLD generic domains has increased – you are free to choose from .blog .beer, etc.

Sponsored Domain Extensions

This type of domain extension is limited to specific kinds of institutions and companies. Sponsored Domain Extensions (SDE) are becoming more and more common today. They secure your online identity while simultaneously promoting your site. 

Generic-Restricted Domain Extensions

This kind of domain extension is restricted to certain types of websites. The extensions policy allows ICAAN registration, ownership of a domain name, registration of a domain name after it has been registered to a party, or transferring a domain name to another registrant. However, if an organization wants to receive authorization to use a domain after the transfer, it must apply for the change from the registrar of the domain and provide an explanation of the intended use.

Country Code Domain Extensions

Country code domain extensions are the country code extension of the domain, e.g., .us or .uk. When you register a domain name, the registration process will ask you which country you want your domain to be affiliated with. Countries assign codes to the top-level domain of their country to denote the country in their domain name.

What are the Most Common Domain Extensions?

It’s important to know the distinctions between meanings of domain name extensions. There are lots of options under the domain name extension umbrella, and many can be confusing. But if you know the difference between a TLD, dot-com, and GTLD, you’ll be better equipped to make the most out of the domain name you’re after.

How to Choose the Best Domain Extension for Your Website

The domain extension you use won’t make any difference to how your website performs, but using a specific extension can make a difference in how your website’s visitors perceive your website. Generally, you should try to get .com for the selected domain, and if it is not available, .net may fit just as well. But first, you should learn what domain extensions mean.

However, remember that you need your domain to be easily distinguished. If a person doesn’t recall your domain name extension, they’ll probably enter .com. If this will eventually lead to a competitor’s website or a blank web page, you may lose that user for good.

But with millions of websites on the internet, picking a good domain extension for your website can be daunting. The internet is essentially one big infinite web, with more links than you can shake a stick at. 

If you own a domain extension and are looking for ways to distinguish yourself from your competition. You may want to consider inventing your own domain extension. You can apply for your custom extension, but first, you’ll need to wait till ICANN is open for applications.
