Understanding Domain Terms: Registry, Registrar, Whois, ICANN, and Aftermarket

Domain names are essential for every website as they provide an identity and a unique address on the internet. However, the domain industry is complex, and terms like registry, registrar, whois, ICANN, and aftermarket can be confusing for beginners. This blog post aims to explain the meaning of these terms and how they help the domain industry.


A registry is a database that contains all the information about a particular top-level domain (TLD). For example, the registry for .com TLD is managed by Verisign, which maintains a record of all the .com domain names that have been registered. Only a few companies are authorized to operate a registry for specific TLDs, and they are responsible for managing and maintaining the domain names within their TLD.

Registries ensure that domain names are unique, and there are no duplicates. They also control the technical aspects of the domain name system, such as DNS servers and IP addresses, to ensure that domain names can be accessed on the internet.

Furthermore, a registry collaborates with registrars to allow individuals or businesses to register domain names within their TLD. Registries provide a set of rules that registrars must follow to maintain the integrity of their TLD.


A registrar is a company that provides domain registration services to individuals or businesses who want to register a domain name. Registrars act as intermediaries between domain registrants and registries, allowing anyone to purchase a domain name and manage it.

When you register a domain name, you do it through a registrar. Registrars offer various domain-related services, such as domain name transfers, DNS hosting, and privacy protection. They also ensure that your domain name is registered correctly and that you have full ownership and control over it.

Registrars charge a fee for their services, and the price may vary depending on the TLD and the registrar you choose. Some popular registrars include GoDaddy, Namecheap, and Google Domains.


Whois is a protocol that allows anyone to look up domain registration information, such as the domain owner’s name, email address, and phone number. It is a public database that contains all the domain registration records.

The Whois protocol was developed in the early days of the internet to ensure that domain name owners could be contacted in case of technical or legal issues. However, over time, some privacy concerns arose, as some domain owners did not want their personal information to be publicly available.

Today, many registrars offer domain privacy protection services that allow domain owners to keep their personal information private while still complying with ICANN regulations.


ICANN stands for the Internet Corporation for Assigned Names and Numbers, which is a non-profit organization that manages the domain name system. ICANN is responsible for coordinating the domain name system to ensure that domain names are unique and accessible on the internet.

ICANN also manages the allocation of IP addresses and other technical aspects of the internet infrastructure. It works closely with registries, registrars, and other organizations to ensure that the internet remains secure and stable.

ICANN is funded through fees paid by registries and registrars and has a global reach, working with stakeholders from all over the world.


The aftermarket refers to the buying and selling of domain names after they have been registered. It is a thriving industry, with some domain names being sold for millions of dollars.

Aftermarket sales occur when domain owners decide to sell their domain names to others who may be interested in using them for their website or business. The value of the domain name depends on factors such as the length of the name, the TLD, and its relevance to a particular industry.

There are several online marketplaces where you can buy and sell domain names, such as NameGulf, Sedo, and GoDaddy Auctions. Many domain investors specialize in buying and selling domain names and have made a significant profit from this industry.

The Importance of Choosing the Right Domain Name

Choosing the right domain name is crucial for any website or online business. A good domain name should be easy to remember, relevant to your business, and easy to spell and type. It should also be unique and not infringe on any trademarks or copyrights.

Having a good domain name can improve your website’s search engine ranking, as well as make it more memorable to your visitors. It can also help you establish your brand and differentiate yourself from your competitors.

Therefore, it is essential to take the time to choose the right domain name and register it with a reputable registrar.

The Future of the Domain Industry

The domain industry is constantly evolving, and new TLDs are being introduced regularly. The introduction of new TLDs provides more options for domain owners and can also improve the availability of good domain names.

However, the domain industry also faces challenges, such as cybersecurity threats and privacy concerns. Therefore, it is essential for stakeholders to work together to ensure that the domain industry remains secure and accessible to everyone.

Understanding the domain industry is essential for anyone who wants to register a domain name or start an online business. Knowing the meaning of terms like registry, registrar, whois, ICANN, and aftermarket can help you make informed decisions and ensure that your domain name is registered correctly and securely.

Moreover, as the domain industry continues to evolve, it is essential to stay up-to-date with the latest trends and developments to ensure that you are getting the most out of your domain name.
