What is a Domain Name?

A domain name usually refers to the name of a website, such as www.google.com, which is what you can see on Google’s website through its web browser.

Think of the website as your home and the domain name as your address.

We know that the internet world is like a whole spider’s web, spanning the globe. A collection of interconnected computer networks that are open to the public. Every computer and every website has an IP Address (Internet Protocol Address) which is very difficult to remember. It is a series of numbers that identify a particular computer on the Internet.

For example my IP address is and my website name is EarningVision.com (Earning Vision). If you search it in the address bar of the web browser, you will see my website. Domain names were invented to solve this problem.

Different types of domain names

Each root domain has two parts. The name in one is the extension in the other. For example www.facebook.com where Facebook is the website name or domain name and .com is the extension. These extensions are selected by country according to the name of the website and the type of organization. For example-

  • .com is the most commonly used extension. Which is 46.5% of all websites in the world used this extension. It is commonly used for commercial websites.
  • .in, .bd, .uk These are country specific domain names like .in for India.
  • .info is used for informational websites.
  • .org is used on the website of an organization.

These are again divided separately.

TLD: Top Level Domains

These are all top-level domains. Extensions of these domains whose names are listed at the highest level of the system. There are over a thousand TLDs, but the most important ones are .com, .org, .net and .edu.

When the Domain Name System was created in the 1980s, the domain name space was divided into two main groups.

ccTLD: Country Code Top Level Domains

These domains are used as country specific domain names. These domains are usually two characters long. Ending with country code extensions like .bd for Bangladesh, .in for India, .uk for United Kingdom.

They are used by a website that wants to reach internet users in certain countries.

gTLD: Generic Top Level Domains

Generic top-level domains identify top-level domain names.

Identifies which domain will be used in which organization. such as

  • .com (Commercial)
  • .org (organization)
  • .net (network)
  • .biz (business)
  • .info (information)

sTLD: Sponsored Top Level Domains

Specific level domains are further subdivided into specific uses sponsored by agencies or organizations. For example-

  • .gov (for Government websites)
  • .edu (for Education Websites)
  • .int (for International Organization Websites)
  • .mil (for military websites)

Second Level Domains

Second level domains always have another ccTLD domain extension added next to the gTLD domain. Used to identify specific websites in specific countries. For example-

  • .gov.uk (for United Kingdom Government websites)
  • .gov.in (for Government website in India)
  • .ac.us (for US academic websites)


A subdomain is another part of your website or another part of the main domain. No separate payment is required for this. For example, Google’s search engine website is google.com and play.google.com is the Google Play Store website. Google.com is the main domain and play. is the subdomain.

Who manages the domain name system?

The Internet Corporation for Assigned Names and Numbers (ICANN) manages the domain name system. It is a non-profit organization. This organization allows companies called domain name registrars (GoDaddy, Bluehost) to sell domain names and creates and enforces policies for domain names.

How do domain names work?

The main function of a domain name is to enable you to locate the server where your website is hosted. The computer on which your website information is stored is called a web server. Every computer has an IP address. Anyone without a domain name who wants to visit your website must enter the website by typing the full IP address into the browser.

When you search by typing a website in the address bar of your browser. Then your browser starts looking up the IP address of that website in the DNS server. It then sends a request for website information to the web server with the IP address. Then the website appears live in the browser.
