TABLE OF CONTENTS
When choosing a domain name, one of the key decisions you’ll make is picking the right domain extension. This is the last part of the URL that follows the domain name, for example, .com, .net, or .org, etc. Read on to understand the different types of domain extensions, their purposes, and how they are structured.
Types of Domain Extensions
- TLDs (Top-Level Domains)
TLDs are the highest level in the domain name system hierarchy, and they appear at the end of a domain name, such as '.com', '.org', or '.net'. They can serve as an indicator of the type or category of a website, such as commercial (.com) or organization (.org).
TLDs are broadly categorized into two main types:[Component][List][Markers] Custom - gTLDs (Generic Top-Level Domains) - They are the most commonly known TLDs and are not restricted to any specific geographic location or purpose. Examples include '.com', '.net', and '.org'. gTLDs are open to anyone who wishes to register a domain.
- ccTLDs (Country Code Top-Level Domains) - These are TLDs specific to a particular country or territory and could be seen as a digital passport that tells the world where a website is from or your target audience (location-wise). Examples include '.in' for India, '.uk' for the United Kingdom, and '.ca' for Canada.
- Legacy TLDs
Legacy TLDs are some of the oldest and most established domain extensions on the Internet. They were initially intended for specific types of organizations, but have now become general-purpose. They are called ‘legacy’ because they were part of the initial Domain Name System (DNS) established in the 1980s and have been around since then. These include:
[Component][List][Markers] Custom - .com - Originally intended for commercial entities but now open to everyone, it’s the most popular TLD globally.
- .org - Originally for non-profit organizations, but also open for general use.
- .net - Initially intended for network-related organizations, now commonly used for various purposes.
- .gov - Reserved exclusively for government entities.
- .edu - Reserved for educational institutions.
- .int - Reserved for intergovernmental organizations like the World Health Organisation (WHO)
These TLDs have a long history and are widely recognized and trusted by users worldwide.
- New gTLDs
ICANN introduced New gTLDs to provide more options and foster innovation. These new extensions are more specific and can be tailored to industries, interests, or geographic locations. Examples include:
[Component][List][Markers] Custom - .tech - Ideal for technology companies and startups.
- .shop - Perfect for e-commerce sites.
- .nyc - Geared toward businesses and individuals in New York City.
- .earth - Perfect for an environmental non-profit.
New gTLDs allow businesses and individuals to create more relevant and memorable domain names that reflect their identity or niche.
ccTLD Structure
- Standard ccTLDs
ccTLDs consist of two letters and represent a specific country or territory. They are assigned based on the International Organisation for Standardization (ISO) 3166-1 alpha-2 country codes.
You should note that each country may set its policies regarding the registration and use of its ccTLD. However, the majority are open to a global audience, while some are restricted to only residents. For example :[Component][List][Markers] Custom - '.in' - Represents India. A domain like 'example.in' signifies that the website is associated with India.
- '.us' - A website with a .us TLD automatically tells you it originates from the United States.
ccTLDs are often preferred by businesses and individuals seeking to target audiences in a particular country and could be used to increase trust and credibility among the local market. - Second-Level ccTLDs
Some countries use a second level of domain extensions beneath the ccTLD. This creates a structure within a country’s domain space, where domains are registered under a second-level that comes before the ccTLD. Examples include :[Component][List][Markers] Custom - .co.uk - Represents commercial entities located in the United Kingdom
- .co.in - A second-level domain under '.in', often used by commercial entities in India. For example, 'example.co.in' indicates that the domain is intended for business purposes within India.
- .ac.uk - Used for academic institutions in the United Kingdom.
- .gov.au - Reserved for government organizations in Australia.
The structure of a second-level ccTLD often reflects specific categories or sectors within the country, providing clarity and purpose to the domain name. They could also be a great branding opportunity, as their specificity could create a domain name closely associated with your business.
