What are the DNS Records and its uses ?

First we will see, what are the DNS Records ( We can also say it as DNS Entries):


Without going in Complexity and Technical Language, 
we can say that DNS Records are the records which helps to work Online Services. 
( It is enough to know the use of DNS Records, if you want to go into deep or more clarity, you can continue reading)

Online Services includes following services,
Websites ( Online Shop, Online Data Transfer, Bank Services)
Email services 
Mobile Applications


Before explaining more about DNS Entries, have you ever think about how this website works (or any website we use). We place our data at one server, and that data can be access from any corner of world and at any time. How it works?

For Example : (This is very easy example to understand)

Consider, You have one website. 

So, to make any website you need two things:
1. Domain Name ( what is Domain Name)
2. Hosting  ( What is Hosting)


So, whenever we hit our domain Ex. www.amchannel.in in any browser, it takes to specific server (where we have placed the data of our website) whose IP Address is Ex. 192.168.1.11.

To reach our domain name www.amchannel.in to server whose IP Address is 192.168.1.11, 
it requires the DNS Record that record is called as "A - Record", which is added in DNS Server ( DNS Server maintains a directory of domain names and translate them to Internet Protocol (IP) addresses).

Entry Format of "A -Record" is as below:
Format = DomainName    TyperOfRecord  RecordContent   TTL
 Example = amchannel.in      A                      192.168.1.11          7200 

Where TTL = Time To Live ( which is time to propagate the entry in DNS Server, it may be different for different type of records or as per service provider) 

It is the way, how DNS Entries help to reach our server.

And there are various types of DNS records, which are used for various purposes.
When you read more about various types of DNS Record Types you'll get more clear understanding of their uses.
