what is a domain extension

TLD is an abbreviation fortop-level domain,’ and it refers to the last component of any domain name. 

For example, the domain name extension in ‘Zacohome.com’ is .com, while the domain name is Zacohome. 

What Is Domain Extension?

A top-level domain (TLD), also known as a domain extension, is the suffix that appears after the domain name in a web address; the most common one is “.com“.

TLDs are governed by the Internet’s Domain Name System (DNS), which rules how domain names are turned into IP addresses.

Other frequently used TLDs include:

  • .edu
  • .info
  • .biz
  • .co
  • .gov
  • .mil
  • .me
  • .net

How Do TLDs Work?

To load a website correctly, servers have to go through each part of a domain name to find the information they need. The top-level domain is the first part.

There are 13 root name servers that hold all the information for all the TLDs in that domain.

For example, the name server for .com will include information about zacohome.com but nothing about zacohome.co.uk.

As a result, TLDs play a significant part in the DNS lookup process. When a user enters a domain name such as ‘zacohome.com’ into the browser, the DNS resolvers begin the search by interacting with the TLD server.

Because the TLD in this example is ‘.com,’ the resolver will contact the TLD DNS server, which will supply the resolver with the IP address of zacohome’s origin server.

What Are the List of Top 5 Domain Extensions?

When you’re looking for a new domain name for your site, you should know about three types: generic, sponsored, and country code.

Generic domain extensions

This is the most common type of extension, and it is what most internet companies use in their domain names.

Generic domain extensions are available to any website willing to pay for them, and some are even available for free.

The popular extensions .com, .org, and .net, as well as many other specialty TLDs, are generic.

Sponsored domain extensions

Sponsored domain extensions are only available to organizations that meet specific criteria.

For example, only accredited educational institutions can use the .edu domain suffix for their websites, whereas the.gov extension is only available to companies affiliated with the United States government.

Country code domain extensions 

Many nations have their own two-letter domain extension to indicate the location of a business. .us (United States), .uk (United Kingdom) ,.de (Germany), and .sg (Singapore) are some examples.

Here are the five most common TLDs:


The .com domain extension is an abbreviation for “commercial.” When it was first introduced, .com was meant for eCommerce sites.

It is now the most commonly used domain extension, accounting for more than half of all websites. Many consider it to be the default domain extension.

The Cheapest .COM Domains can be purchased from as low as S$11.88.


After .com, .net is the second most common TLD. It is an abbreviation for “network” and was designed for websites that specialize in network-based technologies, such as ISPs, email services, and database services.

In recent years, .net has occupied the same domain space as .com.

Search domains for business in the networking technology industry with .NET Domains, just start from S$18.90 with free DNS management.


This TLD was created for and is only available to charitable organizations, hence the suffix “.org.”

While this limitation was recently relaxed, the original aim remains — .org is commonly used by foundations and charities, educational services, open-source software projects, and other non-profit organizations.


To alleviate the scarcity of desirable .com domain names, the .co extension was introduced in 2010.

It is an abbreviation for “company” or “corporation.” .co, like .com and .net, is the most popular domain among internet companies.

.biz is reserved for internet enterprises, as the name indicates. It’s the least popular extension on the list, but it’s also the least expensive.

Despite being a generic domain extension, the .biz TLD is only available for business and retail websites.

When to Use an Alternative TLD

There are now hundreds of TLDs available, ranging from the popular domain extensions .com and .org to things like .io, .guru, and .florist.

There is a reason why the number of domain extensions will continue to increase. With only .com, the internet is becoming a little congested.

So, when should you stray from the norm and use a different alternative TLD?


When consumers search for a brand on the internet, the first thing they see is the domain name.

As a result, having a lengthy, excessively descriptive domain minimizes the impact that your branded domain name should create.

With more TLDs to pick from, companies now have a better chance of choosing the best domain extensions that accurately describe and communicate the brand’s identity.

For instance, instead of sightseeingwithjacktravels.com, you can shorten it to sightseeingwithjack.travel


A clear domain name tells visitors what to anticipate when they visit your website and encourages more people to click on the website in search results.

It also helps reduce your website’s bounce rate, which will help your SEO.

The reason is that if people know what to anticipate and your content is good, they are more likely to be interested in what you have to offer and will thus stay longer on your website.

For instance, suppose you had a .FLORIST domain and your website is about flowers. Because the name makes it apparent what to expect, it is rare that visitors will misunderstand your business nature.

Brand Protection

If your company currently has a .com domain, it may be worth purchasing the relevant new TLD domains and redirecting them to your main website, or vice versa.

This can help prevent your domain and brand from being replicated online, avoiding brand confusion.

Additionally, you can prevent scammers from phishing your business with a similar domain.

How to Choose an Alternative Domain Extension

Unless you come up with a really original domain concept that is not based on popular dictionary phrases, you will almost certainly discover that someone – potentially a domain squatter – has already registered the .com version of your domain.

After all, there are over 1 billion websites around the globe, and that number is growing by the day.

Don’t give up on your name concept just yet! You have a plethora of alternative domain name suggestions at your disposal to make it a superb domain name.

Let’s compare the difference between domain name extensions to help you choose the best alternative when your first choice isn’t available.

.COM vs .SG

While a generic domain extension like .com may imply a worldwide brand, country code domain extensions like .sg will be well-received if you cater to a local audience. Furthermore, search engines favour local websites. 

So, if the name you want is not accessible through the original gTLDs and you do not want to use a new gTLD, but rather something more traditional, you can register a domain with a ccTLD.

Zacohome.com.sg or zacohome.sg are good examples.

.COM vs .CO

Both .co and .com are domain extensions for internet companies. First and foremost, aim to get a .com extension for your selected domain.

If the .com extension is not available, .co is a well-known TLD option, but it will take more effort to brand your website effectively.

.XYZ vs .COM

If users will not manually type your domain name into their browser’s address bar, using .xyz as a top-level domain is a good choice.

However, visitors may be more aware of fraud since they probably encounter fewer .xyz TLDs compared to .com TLDs.

As users become accustomed to seeing the hundreds of TLDs that have been published in the past few years (.xyz among them), their scam radar will become less sensitive.
