Today we can access internet very easily, can open any website in our browser, can remember the name of almost all the websites of our work, all this has become possible only because of DNS, without DNS you can use modern Can't access the internet and can't search your favorite websites.
We use DNS everyday in our daily life but very few people have enough knowledge about DNS. If you have a little understanding of technology, then you must know that computers do not understand human language, they can only understand numbers.
Whenever you search in the browser to open a website or webpage in the Internet, then to understand your request, the computer needs a number called IP address and DNS is the IP address of the website you searched. Converts to and explains to the computer.
The full name of DNS is Domain Name System or Domain Name Server. That is, DNS is a kind of system or server that manages many Domain Name's!
“DNS is a system used in the Internet that converts domain names to IP addresses.” It is only through DNS that we can connect to that website by searching the domain name of any website in the web browser as per our wish and can access the website.
All the devices that use the Internet have their own unique IP, which is in the form of a number, such as (184.108.40.206). This IP address is machine readable. But it is not possible for a human to remember the IP address of all the websites present on the internet, hence the domain name has been created. Domain names are in the form of words that humans can remember.
When the user searches any domain name in his browser, then DNS converts that domain name written in words into an IP address, and then understanding the computer IP address, shows the website on the browser in front of the user.
Simply put, DNS is a system that translates domain names into IP addresses understood by computers.
The Domain Name System (DNS) was invented in the year 1980 by American computer scientist Paul Mockapetris. When the Internet was started, so many websites were not present on the Internet, so any website could be accessed only through IP address.
But gradually the Internet developed and its size also increased, so many websites were created on the Internet that it became impossible to remember them by IP address, DNS was started in view of these problems. With the advent of DNS, the user was able to access the website as per his choice.
If you still do not understand What is DNS? well, then understand the functioning of DNS very well. As we told you above, everything that is connected to the internet like website, computer, server, smartphone, etc. all have a unique IP address. This IP address only identifies each device for communication through the worldwide web.
Since IP addresses are in the form of numbers, it is difficult for a common man to remember them. To solve this problem, memorable domain names for humans were created. But the machines understand only the IP address, so a translator was needed which could convert the domain name into an IP address and explain it to the machines. This translator is called DNS.
When the user searches any domain name in his browser (such as www.example.com), then DNS converts this domain name into an IP address.
By understanding the computer IP address, it finds out which website the user wants to access and connects the IP address to the host server of that website. After which the www.example.com website opens in the user's browser and the user can access it.
You can understand DNS like the phonebook of the Internet because it works like the phonebook of your mobile. Just like you save all the contact numbers in your phonebook by name and to call or message a number, remember the name in place of the number and search the name in the phonebook as well, similarly any website in the Internet To access the domain name is remembered instead of the IP address. So DNS works in this way.
After understanding What is DNS?, let us now understand DNS records as well. Domain name and IP address information is present with DNS in a systematic manner which is called DNS Record. DNS records can be of many types like A, AAAA, MX, TXT, CNAME etc., the work of all these is also different.
There are mainly 3 types of DNS servers.
There are many types of DNS Records! So let's know some commonly used DNS Records!
|IPv4 Address record
|IPv6 Address record
|Canonical Name Record
|Mail Exchanger Record
|Pointer Type Record
|Start of Authority Record
|Service Location Record
