Basically, DNS makes it easier for people as end users of the Internet to connect to a website in a more efficient and effective way.

Because with this mapping system, the human only needs to type the domain name of the suitable website without having to remember the IP address of the website, which is a series of random numbers that are difficult for humans to memorize.

For example, YouTube's IP address is and YouTube's domain is youtube.com.

Do you find it easy to remember YouTube URLs? You're going to answer youtube.com, right?

This is where the role of DNS becomes very important for the existence of a website or any other site.

So, do you want to know more about mapping because its existence is magical for humans and computers at the same time?

Thank you for coming to the right article because we will fully explain what DNS looks like, its functions and how it works on the Internet.

Understanding DNS

The Domain Name System, or better known as DNS, is a system that maps and translates IP addresses so that Internet users can access websites easily, quickly, and securely.

It is important to understand that every device connected to the Internet, such as laptops, tablets, and smartphones, has a unique IP address that other machines use to locate the device.

Instead of remembering IP (Internet Protocol) addresses, you can find information online through domain names like domain resellers. rna.idThen the web browser is connected through the IP address.

The domain name forms a URL (Uniform Resource Locator) that receives client requests.

This mapping system translates domain names into IP addresses so that browsers can search and process Internet resources.

Used as an example, DNS stores all important numbers from a specific person or agency, much like an Internet phone book.

DNS function

Among the many explanations of what DNS is, its important functions on the Internet are as follows.

  • Translates hostnames and domain names to IP addresses, and vice versa.
  • Search and find IP address information based on domain names.
  • Accessing website data and information based on the database server for display in the client's browser.
  • Find the right server for the email delivery process.
  • Requests website URL information based on the IP address entered by the client.
  • Secure the transfer of customer data as long as the customer uses a specific website

How DNS works

As a system, DNS operates in user-initiated and user-terminated sequences.

When you type a domain name, for example jasa.com, into your browser's URL bar, your browser sends a request to the Internet to find the jasa.com website.

A query is an expression of data to search for a domain name and return the corresponding IP address.

The first server to connect to your request is a repeater run by your Internet Service Provider (ISP) as a wireless operator or third-party provider.

A recursive resolver is a server designed to receive requests from clients via a web browser.

A frequent query server can be thought of as a librarian who is asked to search for a specific book in a library.

This server is then responsible for making additional queries to satisfy the client's DNS queries.

The recursive resolver knows which other DNS servers to query to answer the query statement for the IP address contoh.com.

The recursive resolver communicates with the underlying server. A root server is the first step in DNS to translate human-readable hostnames into IP addresses.

Root servers are similar to databases running on websites around the world, and each one is aware of information. Domain naming system Top Level Domains (TLD) such as .id.

To start answering user queries, the Resolver server asks the root server for DNS information.

To date, there are thousands of servers supporting root servers in various locations around the world.

This mapping system ensures that your request is sent to a server that is not too far away from your location when you access the website.

A name server TLD can be thought of as a separate bookshelf in a library.

This name server is the next step to get a specific IP address, and it contains the last part of the host.

Each TLD name server stores DNS information for secondary domains or SLDs (example.com) within the TLD (.com).

When your request reaches the TLD name server, the TLD name server responds to your request by providing the IP address of the domain name server.

Next, the recursive resolver server sends queries to the domain name server, or DNS server, which is the host server.

For example, it knows the IP address.

  • A user request website display is displayed

Now the Recursive Resolver server knows the IP address of the domain name, and the Recursive Resolver server tells your browser which website corresponds to that IP address.

Finally, your browser can send requests to websites to retrieve specific website content using the IP address it has just acquired.

Importance of DNS for website domains

The hope is that through this article you will be able to understand more about DNS in theory and how it works on an Internet network.

The main point of domain mapping system benefits that are felt by people as end users of the internet is the ease and security of the process of accessing a website.

Then, even if the DNS system or procedure you are unfamiliar with is very complicated, make sure everything is programmed as well as possible so that the browser can handle many transactions efficiently every day.

As long as this system exists, it will continue to work to help ensure that online network connections are more secure, stable, and robust.
