DNS refers to the Domain Name System. Do you know we can’t be able to access or visit web pages as you do without a Domain Name System? If there is nothing like a Domain Name System, you have to remember the long IP address of web pages like 192.168.1.1.

Domain Name System plays a promoting role for internet networks. Furthermore, technology has made our lives simpler. But how knowing about the DNS servers can help you? 

Well, in this digital era, you should know what DNS is and how it works. Furthermore, knowing about DNS servers can benefit you greatly when it comes to creating and developing a website.  

What Is DNS Server? 

You can think of the DNS server as your phonebook, where you save many of your near and dear ones with their name. You can do so when you need to call someone by selecting his name in the phonebook. You neither need to remember his number nor dial it. 

Now, you have to relate the concept of your phonebook with the DNS server. The domain name system server stores billions of domain names with their IP address and shows you search results based on the domain name of the IP address you put on the search bar. 

Here, you don’t need to remember the long-form IP address. Each device of the server has a unique IP address for one website. Millions of people visit Google every single second. Here, all the devices used to visit Google have different IP addresses. 

How Does DNS Server Work?

You may be curious about knowing how the domain name works and less than a second. As you don’t need to remember the IP address of a particular website you want to visit, you have to put the URL or domain name of the server in your search box. 

Once you put the website’s domain name on the search bar, the request to find the IP address of the domain name is routed to the DNS resolver server. Then the DNS resolver server finds the IP address of the domain name in its server, 

Moreover, if the DNS resolver server can’t find the IP address, it then forwards the request to the TLS.name server. The TLD.name server then sends the request to the authoritative name server, which is the final destination of the request for the expected IP address of the website. 

Then, the authoritative name server sends the IP records to the DNS resolver server of the ISP. Thus, you can visit the website you want to visit. Furthermore, in most cases, you don’t need to type the entire URL and domain name to revisit that website.

The DNS resolver server cache the IP record, and whenever your search query becomes relevant to your previous search, it suggests the website or web pages. However, the servers play the most significant roles in the DNS system for performing specific tasks.
