TLD stands for ‘top-level domain’ and refers to the rightmost part of every domain name. In namecheap.com, ‘namecheap.com’ is the domain name, and ‘.com’ is the TLD. If you’re looking for a TLD, check out our top-level domain list to see what you can register, or try our domain name search.
If you are brimming with questions like ‘What is the purpose of a TLD?’, our handy guide is here to provide the answers.
It’s now time to get started and define the top-level domain extension. Still unsure of what are top-level domains in a URL? Let’s use an example.
Consider namecheap.com again. When you type it into your search bar, our website is being located by your computer, using the domain name and an IP address.
Every website on the Internet can be identified by an IP address, which is a unique series of numbers. These numbers are a set of instructions that allows a computer to access stored website data.
Think of an IP address as a mobile phone number. While you may have ‘Dad’ listed in your phonebook, it’s the number that you ultimately use to connect with him.
The letters at the end of a website address are known as its top-level domain (TLD). They typically tell a story about the domain name associated with it, such as the geographical area it was created in, its purpose, or the organization that owns it.
So, what is an example of a top-level domain? There’s .ca for Canada, .biz for businesses, and .com for commercial websites. Interestingly ‘top-level domain’ is also known as a ‘URL extension’.
Although the most popular TLD is .com, there are many others available, including .info, .dev, and even .pizza.

The original top-level domains were developed in the 1980s and were divided into three groups, Categories, Multi Organizations, and Countries.
Every original TLD had a unique purpose:
| Name | Entity |
|---|---|
| .com | Commercial |
| .org | Organization |
| .int | Intergovernmental organizations |
| .edu | Education |
| .gov | Government agencies |
| .mil | U.S. military |
These days this restrictive practice has been largely lost, the meaning of domain extensions changed, and top-level domains are used in a variety of different ways. Domain registration is mostly open for all, apart from gTLDs assigned for the government, such as .gov and .mil.
So, what are a gTLD and ccTLD anyway, and what’s the difference between them?
Generic top-level domains, (gTLDs) account for the majority of domain extensions. The most common gTLDs are .com, .org,and .net.
Country code top-level domains (ccTLDs) are location-specific and are generally reserved for countries and some territories. Examples include .us, .co.uk, and .de.
Since 2014, ICANN has released over 2,000 new extensions covering all areas from clubs and hobbies to industry, science and technology, and geographic locations. The addition of new generic top-level domains has taken some of the stress off the original gTLDs.
Interestingly, the mighty .com remains one of the world’s most popular and most recognized gTLD, perhaps because it was one of the original top-level domains. Buyers place huge value on .com domain name price over the new extensions, simply because of its universal recognition.

Hold onto your hats and let’s delve into the nitty-gritty of top-level domains. To successfully load a website, computers need to work through each section of a domain name to locate the data needed, starting with the top-level domain.
There are 13 root name servers that contain all the information for all of the gTLDs within that domain. For example, the name server for .com will contain information about amazon.com, but won’t contain any information regarding amazon.co.uk.
So who is responsible for managing top-level domains?
The Internet Corporation for Assigned Names and Numbers (ICANN) delegates the responsibility for the global coordination of domain names.
A non-profit corporation, the Internet Assigned Numbers Authority (IANA), is a department of ICANN. IANA assigns TLDs with IP addresses, which are vital for a domain to be discovered online.
If you’ve been paying close attention, you’ll know that there are different types of internet domains, and you already know the answers to the following questions:
Just in case you missed it the first time, gTLDs are generic top-level domains, and ccTLDs are country code top-level domains — geographical domains that are associated with a particular area in the world.
For example, the TLD .de is associated with Germany, .io with the British Indian Ocean Territory, and .us for the United States.
Generic top-level domains are the largest group of TLDs and account for most of the newly available domains. There are older, well-known gTLDs like .com, .net, and .org, and newer options, like .club, .accountant, and .pizza.
Ideal for companies and individuals, gTLDs can help you depict what your website actually does.
In 2019, the 5 most common domain extensions according to Verisign were .com, .tk, .cn, .de, and .net. The .com remains the king of domain names, as one of the original and most popular top-level domains, it’s instantly recognizable.
If you haven’t registered one of the most common top-level domains however, it doesn’t mean that you’re automatically at a disadvantage. The beauty in having the opportunity to choose from a large array of domain names means that it’s very easy to find one that fits your purpose, whether you’re choosing from common TLDs or the more obscure.

If you fancy trying your hand at creating a brand new top-level domain for people to use, the first step is to apply to ICANN. If your registration is successful, you’ll become a registrar and have the ability to decide who can use their domain on your TLD.
Some TLD applications can be quite contentious. For example, Amazon has applied for .amazon and have waited years for a decision over their registrar status. ICANN has been dragging their feet due to concerns from countries with Amazonian regions, fearing specific .amazon domain names could cause confusion or touch on national sensitivities.
When a name is reserved, it can only be registered by the parties who hold the reservation. Reserved names aren’t operational URLs until registered. Domains can be reserved before they go live, others are available for immediate registration and some aren’t open for public registration.
