As the internet corporation expands in size and complexity, businesses and services must establish a recognizable brand identity to reach a broad audience. Custom domain names serve as your digital home, making it easier for users to find and connect with you.

Whether you aim to grow your business name, want your voice heard, or wish to have your website, creating a solid brand and securing a registered domain address online is essential.

Domain Name Overview

A domain name is a unique, human-readable address used to identify a website online. Instead of remembering complex IP addresses, users can readily recall and input domain names, like google.com, to reach a specific site. Domain names have two main parts: the second-level domain (SLD) and the top-level domain (TLD). In google.com, “google” is the SLD, and “com” is the TLD.

A domain registrar is an entity that manages the reservation of domain names.

Some hosting providers offer a free domain name with their plans, making it easier for new users to get started.

In other words, it’s a unique identifier for an internet user’s website, pages, or email account.

But before we discuss how a domain name works, let’s define some basic yet overlooked terms in the article that make sense and that others don’t know.

IP Address:

An IP address is a unique numerical identifier assigned to computers on a network. While essential for machines, it takes time for humans to remember. That’s why we use URLs—they’re easier to recall. The domain name is a crucial part of the URL. The Domain Name System (DNS) converts the associated IP address to a URL, making the web more user-friendly for users and search engines.


URL structure with domain name

A URL (Uniform Resource Locator) is the complete web address of a specific resource on the Internet. It includes the protocol (like https://), domain name, and path to a particular page or file. Most URLs are structured around the domain name of the web server that handles client requests.

An example of a complete URL would be: https://bossfacts.com/web-hosting

When you type that URL in the address bar, it will open a page about What Hosting is and its Importance.


DNS (Domain Name System) is a decentralized naming system for computers and services connected to the Internet. It translates human-readable domain names into IP addresses, allowing users to access websites using memorable names instead of numerical addresses.


(Hypertext Transfer Protocol) is the foundation of data communication on the World Wide Web, defining how messages are formatted and transmitted. HTTPS is the secure version of HTTP, using encryption to protect data during transfer between a user

How Does A Domain Name Work?

When you enter a domain name into the address bar of your web browser, a series of steps occur behind the scenes (in seconds) to direct you to the desired website.

Root servers are the first step in the DNS resolution process.

Here’s a simplified breakdown of the process:

DNS Query

Your browser requests a DNS server to translate domain names into IP addresses. A recursive resolver is a DNS server that processes queries by requesting other DNS servers.

DNS Resolution

The DNS server looks up the IP address associated with the domain name from its database or forwards the request to other DNS servers if it doesn’t have the information.

Authoritative name servers provide the definitive IP address for a domain name.

IP Address Retrieval

Once the IP address is found, it is returned to your browser. A DNS cache stores IP addresses to speed up future queries.

Connecting to the Server

Your browser uses the IP address to communicate with the web server hosting the website. Web hosting is the service that allows websites to be accessible online.

The server responds by sending the website’s data to your browser, which then displays the web page. This is where the IP address turns into a URL for internet users, making it easier to access the website.

Loading the Website

This entire process happens instantly, allowing users to access websites quickly and efficiently. A browser cache stores website data to speed up future visits.

Now we understand how the domain name system works, let’s look at the types of domain names.

Types of Domain Names

types of domain names

There are several types of domain names, each serving different purposes:

Top Level Domains: Top level domains are the highest level in the internet’s hierarchical DNS. They are divided into two main categories: generic top-level domains (gTLDs) and country code top-level domains (ccTLDs).

Generic Top-Level Domains (gTLDs): These widely recognized domain names include .com, .org, .net, and newer options such as .app and .blog. They are the most common type of domain extensions.

Country Code Top Level Domains (ccTLDs): Country-specific TLDs are domain extensions designated for specific countries or regions, like .uk for the United Kingdom and .jp for Japan.

Second-Level Domains: Second-level domains exist directly under a TLD and often represent a brand, organization, or individual, such as example.com.

Registering the same domain name with different extensions can future-proof branding and ensure consistency across various platforms.

Third Level Domain: A third-level domain is a subdivision of a second-level domain in the Domain Name System (DNS). It’s created by adding another label to the left of the second-level domain, forming a hierarchy. For instance, in subdomain.example.com, “subdomain” is the third-level domain under “example.com.”

Understanding DNS: The Internet’s Phonebook

DNS, or Domain Name System, is a crucial internet infrastructure component. It functions as a decentralized directory that translates human-readable domain names into IP addresses that computers use to identify each other.

Here’s how DNS works:

  • When you enter a domain name in your browser, your computer checks its local cache for the corresponding IP address.
  • If not found locally, it sends a request to a DNS resolver, typically provided by your Internet Service Provider. A DNS resolver is a server that processes DNS queries from users.
  • The recursive resolver then queries a series of DNS servers, starting with the root servers, then top-level domain servers, and finally, the authoritative name servers for the specific domain.
  • Once the IP address is found, it’s returned to your computer, allowing your browser to connect

Difference Between a Domain Name and a URL

A domain name is like a virtual home or location for your online presence. Just as you need a physical house with a physical address to live in a neighborhood, you need a domain name to exist on the internet. Think of it as your unique identifier in the global online community.

Domain name registration is the process of reserving a domain name for use. You typically acquire a domain name from a registrar, much like purchasing a house through a real estate agent. Without a domain name, you’d have no fixed location on the World Wide Web.

A URL, on the other hand, is the complete web address where your domain is located. It’s like a street address, with your domain name being the house and the IP address serving as the street number.

For example, if Google were a virtual house:

Domain name: google.com

URL: http://www.google.com/

In this section, we now clearly understand some essential terms and functions leading to your domain name and your own website. So why do we need a domain name?

Why Do We Need a Domain Name
