The importance of DNS

TL;DR: The DNS system is an important part of the internet that makes it easier for us to use, helps to keep it organized, and keeps us safe from malicious websites. The next time you visit a website, remember that the DNS is working behind the scenes to help you connect to the website and access its content.

The Domain Name System (DNS) is a system that connects a domain name, like “,” to a website’s IP address, which is a string of numbers that identifies the location of the website on the internet. When you type a domain name into your web browser, the DNS helps to translate that name into the corresponding IP address, so you can access the website.

Here’s a simple example of how DNS works:

  1. You type “” into your web browser.
  2. Your computer sends a request to a DNS server, asking for the IP address for “”
  3. The DNS server looks up the IP address in its database and sends it back to your computer.
  4. Your computer uses the IP address to connect to the website’s server, and the website is displayed in your web browser.

The DNS is like a phone book for the internet. Just like a phone book helps you find a person’s phone number by looking up their name, the DNS helps you find a website’s IP address by looking up its domain name.

The DNS system is important because it allows us to access websites using easy-to-remember domain names instead of having to remember a string of numbers. Without the DNS, we would have to type in a website’s IP address every time we wanted to visit it, which would be inconvenient and difficult to remember.

Here are a few more reasons why the DNS system is important:

  1. It makes the internet easier to use. The DNS makes it easy for us to access websites by using simple and easy-to-remember domain names.
  2. It helps to keep the internet organized. By organizing websites into domain names and IP addresses, the DNS helps to make it easier to find and access the websites we want to visit.
  3. It helps to keep the internet secure. The DNS system helps to verify that the domain name we are trying to visit is legitimate, which helps to prevent us from accidentally visiting fake or spam websites that might try to steal our personal information or infect our computer with malware.
