However, DNS or Domain Name Registration System is one of the important rules the internet has to perform. Meaningfully, if there’s no DNS system, you won’t be able to order your favorite pizza online or call a taxi to reach the desired destination over a mobile app. 

In this short article, we will try to cover the DNS server and its functions properly. 

What is a Domain Name Server? 

You can consider the Domain name as the name you saved in your Phone book. Why do you save your name in the phonebook? This is because you can’t remember all your friends and family numbers. 

In the case of a domain name system, you can search for a website using letters we use to communicate. For example, to re-enter our website, you must type https://tarhibit.com/ in your browser. 

But, unfortunately, the web server can’t understand your language. This means the web server is unable to understand https://tarhibit.com/. Instead, the web server can understand unique IP addresses to identify a website a visitor is looking for. 

The number is where all the IP address of the website is stored, it is called domain name server, and the process the web server shows you are the website you want to enter is Domain Name System. 

How Does Domain Name Server Work? 

When you type any domain name on your favorite browser, you are redirected to a website in less than you blink your eyes. But, the interesting thing is that all the complex processes of the webserver to take you to your desired website take place meanwhile. 

First, when you type a domain name on a browser, the domain name server looks for cache memory on your end. The cache memory is created when you visit a website several times. 

But, if the domain name server can’t find any cache memory, it searches on its system by translating the domain name into an IP address. If any IP address matches with the IP address of the website you want to visit, the domain name server, with the help of the resolving name server, takes you to the website. 

But what if the resolving name server doesn’t have the IP address on its memory> Don’t worry. The resolving name server then sends the request to find the IP address to the Top Level Domain Server or TLD. 

But, in some cases, the TLD server may not know the location of the domain name server. In this case, the TLD server sends the request to the authoritative name server, 

But, how can a TLF server know what authoritative name server to use? The TLD server knows which authoritative name server to use with the help of the domain register. 

Finally, the authoritative name server receives the request, finds the IP address in its cache, and replies to the operating system. The operating system then sends the memory to the browser, which connects the IP address with the domain name you type on your browser.
