Domain Extensions: How to Choose the Right One for Your Business

Whether you run a business or own a blog, or you just want a piece of the internet for yourself, you’ll need to have a digital address, which is your domain. 

At the beginning of the Internet age, domain names were extremely limited. However, by 1984, the first six domain extensions – .com, .de, .edu,, .org, – were established by the Internet Assigned Numbers Authority (IANA). The first two-character country code domain extensions were set up not long after. And in 1998, the extension,.int was added. 

Today, there are thousands of domain names accessible. It is likely you know only a handful of, .gov, .net, .org, and then maybe a few country domain extensions like .us or In this post, you will find out the major types of domain names and ways to select the one that suits your business.

What is a domain extension?

A domain extension, likewise a top-level domain (TLD), is the information towards the end of the web address that specifies the Internet category or country code. 

Example of domain extensions include:

  • for commercial
  • for organisation
  • for government
  • for all educational institutions in situations
  • for the military
  • for a network
  •, .uk, .ca, .nz, .de for countries.

Of all these,.com is the  hardest to secure as it is the most popular. In case you’re looking for a .com domain name and it’s not available, you can find a domain registry service suggesting alternatives such as .uk or .net. 

To understand domain extensions, it is important to know how domains function within IP addresses. Domain extensions or TLDs tell a story of the domain name associated with it, for example the geographical region it was made in, its main idea, or the company that owns it.

What are the types of domain extensions? 

There are four major types of domain extensions or TLDs classified by ICANN. Every one of the classifications is characterised by what the site is related to.

1. Generic top-level domains (gTLD)

These are the most widely recognised types of domain names. For some time, it was possible to pick only between .com, .org or .net. However, in recent years, the quantity of generic top-level domains has exploded. 

Presently you’ll find a great deal of top-level domain names to choose from, such as .lager, .blog, .XYZ, .business or .data. While these non-exclusive domains should be freely attached to the purpose of the website, anyone can register most of these domain names.

2. Supported top-level domains (sTLD)

The sTLD group are made up of TLDs that are sponsored by the government, a business, a group or other particular entity. Some of the most common examples are the government, post-secondary institutions that are accredited by a country’s department of education, or the military. 

However you will also find smaller STLDs, like .jobs reserved for human resource managers and and sponsored by the Society for human resource management, .museum reserved for museums, .post sponsored by the universal Postal union, or .travel reserved for travel agencies and similar businesses.

3. Country code top-level domains (ccTLD)

Another principal classification of top-level domains is country code. The International standards organisation (ISO) maintains a list of globally recognised codes of letters/or numbers that can be used when referring to countries in subdivisions. 

Examples of ccTLD include: .UK for the United Kingdom, .US for the United States, .DE for Germany, .IE. for Ireland, .CA for Canada, .NZ for New Zealand, .AU for Australia, and .FR for France. 

 As outlined in RFC 1591, ‘domain name system structure and delegation,’ these codes can be automatically registered as new top-level domains within the Internet Assigned Numbers Authority (IANA).

4. Framework top-level domain (ARPA)

This is one of the first top-level domain name (TLDs) types that is accessible. It is delegated as an infrastructure top-level domain name, and it is solely used to help operationally basic infrastructural identifier spaces. The .ARPA TLD is jointly managed by ICANN and  Internet Architecture Board (IAB). 

Initially, .ARPA was set up as a transitory area to fill in as a progress component for a lot of host names in the ARPANET that were directed by DARPA. 

The host names were to be eliminated after substitution was made under the classified TLDs, which, .edu, .mil, .net, .co, .gov,
