Top Level Domains (TLD) Categories

Top level domains (TLD) are the last part of the domain name – the short combination of letters that you see after the dot in the address name. Of course, there are many different kinds of TLDs out there, but generally speaking, we can divide them into three separate categories.


A generic top level domain (gTLD) is a top level domain which is used by specific kinds of organizations. But, this is just a theoretical rule because website owners are using these domains for many different purposes. Some of the most popular generic top level domains include .org, .com, .info and .net. Needless to say, even after so many years, .com is still the most popular generic top level domain.


Country top level domain name extensions are extensions related to specific countries or in some cases independent territories. What’s special about them is that they have just two letters. The IANA (Internet Assignment Numbers Authority) is the agency which is responsible for the creation of these extensions. Don’t forget that every country has a specific rule about who can register a domain name which includes their unique code. For instance, in some countries, any person, citizen or not, can register a ccTLD. In others, only residents of the country can do this.


These are probably the least known top level domains. ITLD stands for Infrastructure Top Level Domain Name. They represent provisionary domains which were used during the upgrade of the domain system. They are used even today, but they represent only a fraction of all the top level domains out there.

No matter what kind of top level domain name you want to choose, there are a few things that you should keep in mind when you want to buy one. Obviously, you will have to conduct some research and make sure that the name you’ve selected is completely legal. After that, you must ensure that the domain name that you want to use is not already used by an organization, individual or company. Trademark infringement is a serious lawsuit that can bring serious financial consequences.

Our advice is to stay away from free domain names because they will bring tons of ads and make your website look less professional. There are some exceptions though. However, if you want to transfer the free domain to a paid one later you may lose some of the web traffic to your website.
