Different terminologies in DNS

We all know the importance of websites in this Internet era where every small business also has an online presence. Let us dig deep into the different terminologies in Domain Name Registration or Resolving process

Domain Name

Domain name is an easy to remember address which is unique for a web entity.

The DNS resolves this name to its corresponding IP address and vice versa.


The Internet Corporation for Assigned Names and Numbers (ICANN) is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, Top-Level Domain name system management, and root server system management functions. There is a certain Top-Level Domain (TLD) structure associated with the domain name structure. Primarily, the .edu, .com, .org, and the 244 templates for countries are a part of the TLD structure. The entirety of TLD comes under the jurisdiction of ICANN.


A registrant is the domain name owner who has complete power over the domain. It can be a person or a company who purchased the domain


The ICANN has designated registrars to carry out registration of domains. The complete list of all registrars is available at Each registrar is governed by processes and procedures associated by ICANN. This makes the registration process very similar from one registrar to another. Each registrar will ask you to provide various contact and technical information that makes up the registration. After obtaining the required parameters, the registrar will store the records in its local database and also submit the technical information to a central directory known as the “registry.”


Registry is the central database of domains. This registry provides others with the information necessary to get the information regarding your website.

Name Servers or DNS servers

The Domain name server keeps track of the domains hosted on the server. They also keep the corresponding IP address for the resolution process

Private Registration

If you do not want to share your contact information with the world, you can opt for the private registration.
