What isDNS? how does it work?
What is
Domain name system
If you want
to blog or have some kind of website and you do not know about DNS, then it is
very important to know about DNS. In this post, we have told you about DNS in
such a way that you will be very easy to understand.
Does it
describe what DNS is? how does it work? And about its history.
We know
that many people in the world visit any website at any time. When searching in
a browser by typing the name or URL of that website. And according to our wish,
browse the data or information we need. And we get the same result.
But you
must have tried not to know where and how to get this data. We are going to
tell you about this. And know what is the relationship between DNS and Domain
name?
The
computer does not recognize the human language. Rather it recognizes numbers.
When you want to open a website, it is the name of a site. Then how it opens.
Which is important to know about.
How does
all this happen? Which you will know in depth below.
What is DNS?
DNS-Domain-name-system,
DNS definition
DNS is the
system to manage the domain name of a website.
If it is
talked about the Domain name system definition, then it happens that DNS
contributes to accessing the website. DNS itself reduces the management of
domain names and IP addresses.
The full
form of DNS (DNS full form, full form DNS) is the Domain name system. DNS is a
system that converts domain names to a number such as IP Address. Which
identifies the site.
All the
websites of the world are hosted on a server through online internet. Then when
visited on the site, it reaches the server hosted to be accessed.
The server
is excessed by IP address, not by the domain name. That is, an IP address is
required to open a site and connect to the server.
You cannot
know about a website from an IP address, what kind of website is there. The
most important is that remembering this number of IP addresses is smiling.
Because you cannot remember the IP address of many sites.
In view of
this problem, a domain name system was needed. So that any site can be easily
identified. DNS is required to manage the name of any site through IP address
and to make it more connected by connecting to the server.
History of DNS
When the Internet was started and when very few websites were used, at that time a website was identified from the IP address itself. Whenever a website had to be opened, the IP address had to be remembered.
Then, day
by day Internet usage increased and the number of websites increased
significantly as the network base grew. After which it became difficult to
remember the IP address of many websites.
To tackle this
problem, a computer scientist named Paul Mockapetris invented the Domain Name
System (DNS) in 1980.
The
invention of DNS was considered to be quite controversial and useful. By which
the IP address of a site is opened by not remembering its name. Which became
very easy. This is how DNS was invented. The benefit of which is being given to
all of us today.
How does DNS work?
How DNS
works?, DNS example, what is DNS and how it works
To load the
resources of the site on the Internet translates the domain name to the IP
address via DNS.
When we
want to open the domain name of a website by typing it in a web browser, then
DNS itself converts the domain name into a number to connect to the server and
open. After that, the site opens.
Now you
understand that the task of DNS is to convert the domain name to IP address.
Records of
all domain names in the world are managed by ICANN (internet corporation of
assigned names and numbers).
Through
ICANN, many companies like GoDaddy, Bigrock, Namecheap, etc. have been given
authority to sell the domain names.
Instead of
managing the domain name with ICANN, the domain registrars charge something
every year even after we buy the domain.
We hope
that in this post you must have understood what DNS is what is its history and
how does it work?
