History of DNS

When the Internet came into existence, there were not so many websites, so the websites were identified only by their IP address. But as the Internet developed, many websites started being built on the Internet and it was becoming very difficult to remember the IP address of the websites.

To solve this problem, in 1980, American computer scientist Paul Mockapetris invented DNS. With the advent of DNS, the IP address was given a domain name that the common man could easily remember. This is where DNS started.

How DNS works

As you have understood so far that DNS converts domain names to IP addresses. All the devices in which you can use the Internet have an IP address by which the device is searched on the Internet, just as each house has its own unique address by which it can be easily found. Similarly, the Internet also has the IP address of the device.

When you type a domain name or web address in your web browser, the computer goes through several processes before showing the result in front of you. First of all, DNS converts the domain name to IP address, by which the computer can understand which website the user wants to access.

After recognizing the IP address, the computer searches for the website you have searched in Local Cache. All the information you have recently searched is saved in Local Cache.

If the website is found in Local Cache, then the computer shows the result in front of you in the browser. And if that information is not found in the Local Cache, then the computer sends the request to the ISP (Internet Service Provider). in isp Server Cache contains information about almost all popular websites.

If the computer finds the website searched by the user here, then the computer shows that website to the user and the search ends here.

But if the website is not found here too, then the query goes to the DNS Root name server. Each domain has its own set of name servers.

Complete domain information is available with the Name Server. Domain Name Server reviews the user’s request and forwards it to the Authoritative name server. And after finding out the IP address associated with the domain, it sends the information to you. And you can access the website.

This whole process ranges from typing the domain name in the web browser till the website is opened in the browser. Which does not take even a second to complete.
