What is a Domain Name?

A domain name is the name of a website that is used with a domain extension to identify the website. This domain name is used in the place of an IP address.

We all use the Internet every day. Nowadays internet has become a part of us. A lot of our work is done on the Internet.

  • Watching videos
  • Collecting information
  • Finding jobs
  • Shopping
  • Reading
  • Banking and more

We do not get all these things in one place on the internet. We get it from various sources called websites. For shopping, we visit Amazon, Flipkart, Walmart. For collecting information, we visit Wikipedia. All these websites are located at different web addresses on the Internet, we call this an Internet Protocol (IP) address.

Different IP addresses have been given on the Internet for different websites. These IP addresses are in the form of number series, something like The IP addresses are very difficult to remember for an individual. So, for better access to every website, a name has been used, which is associated with different extensions, it is called a domain name.

How does a Domain Name work?

To understand better how a domain name works, let’s take an example:

If you want to buy something, and you have to visit the Amazon website. Therefore, you must type the full IP address in the URL bar of the browser. It is a little difficult in typing the IP address number series. You can’t even remember the number. If you write “amazon.com” in place of IP address, then you can easily identify and reach Amazon’s website.

There are over 1.7 billion websites on the Internet, and you are probably using some of those websites to get different products, information, or different services. The IP address of all websites is also different. It is very difficult for us to remember the IP address of those websites.

With the help of a domain name, you can easily visit a website by typing only the name in the URL bar of the search engine. When we go to Amazon’s website, we get a URL like this:


Here “amazon.com” is the domain name of Amazon “https://” is the web protocol sign. To visit the amazon website we just need to type the URL “https://www.amazon.com/” or only “amazon.com” in the URL bar or “Amazon” in the search engine box.

The Domain Name System (DNS)


All domain names are controlled by the Domain Name System (DNS). The DNS is like a phone’s address book that saves all-numeric IP addresses in a particular name.

To understand better the DNS let’s take an example:

You have 50 friends in your friend circle and each friend has a mobile number. You saved all 50 mobile numbers on your mobile with their names for identifying every number. When you need to call them, you just go to your mobile directory and search for the name of the specified person, call him. The mobile phone worked as your directory here.

The DNS is just like a mobile directory. It saves every IP address with a particular name called Domain Name. When someone searches a particular website by its domain name on the Internet, it converted to an IP address and takes users to that website.

Now the question is who manages the DNS?

The Internet Corporation for Assigned Names and Numbers (ICANN) manages the Domain Name System. ICANN is a non-profit organization that controls and creates rules for domains. Domain Registrars take permission from the ICANN and sell the domains to the users and controls all records.
