Have you ever wondered how domain names work? How entering a domain name in a web browser leads to the opening of a specific website? Have you ever came across the term DNS and wondered what is DNS? Let’s have a look at how the system works?
What is DNS?
Domain Name System (DNS) is a protocol under which a domain address is converted into an IP address and redirects the browser to a particular web server where the website files are hosted. This server then returns the requested web page and displays it in your device’s browser. A domain name system can also be termed as Directory of the Internet, where it searches for the IP address associated with the specific domain name. Each device connected to the internet has a unique IP address, using which other machines communicate with it.

Detailed Technical Overview:
The domain name system consists of five interconnected elements, namely:
Domain Name
Hosting Server (IP address)
Nameservers
DNS Record
Browser
Domain Name
It is the business identity and is based on the preferred choice of the website owner. A website owner can register any of the available domain names, followed by domain extension, like .com, .net, .co, .org, .edu. Each of these domain extensions is used for specific purposes.
Under the domain settings within the registrar account, you can set specific Nameservers to point the domain to a specific hosting server.
Hosting Server
It is that part of the system where files and database associated with the website are stored. The hosting service provider provides users with a set of DNS records and Nameservers. You have to specify these nameservers or DNS records for your domain to direct the end-users to display the webpage on their browser.
