WHAT IS DNS?
DNS commonly stands for Domain Name System and is an essential tool for input of information in the language understandable by the Internet; known as IP address.
In layman’s terms, it is used to convert the domain name of a network to IP address so that it is acceptable by the server.
For example, www.catsandbats.com is the domain name, for which the DNS server might translate it into its corresponding IP address 22.214.171.124. DNS servers are a network of servers, which operate by mutual communication and translation; i.e., if a server doesn’t know to translate the domain name to IP address, it requests the help of another server and so on until the translation is achieved.
Thus when one server is down, the completion of the task remains unaffected, but the speed reduces. This happens due to delay in the redirection to the requested page.
The term DNS was coined by Bill Gates and was found by Paul Mockapetris in the year 1983.
DNS Servers, What They Are?
DNS servers are nothing but mere computer servers which contain countless public IP addresses and their corresponding hostnames. These are used to resolve and translate these names to the requested IP addresses. It improves the speed of communication between the user and the host of the page that has been requested.
Once you register for a new domain name or change an already existing domain name, it takes 12-36 hrs before updating is done throughout the worldwide domain name servers, and this time is known as propagation time.
What Does Public Mean Here?
As we look through, we might find most of the DNS servers that we use on a daily basis are Private Servers only. This means they provide services only to the companies that own and operates them.
These companies can allow it’s customers to use the services and enjoy its benefits and the cost to be paid by them, is only to be a part of their company, and invest in them for their corresponding benefits.
The clearest and simplest example is the mobile service you use, for which you pay on a prepaid basis. Here, the customers of a specified mobile network service are allowed to access the service of only that network.
For example, an Airtel customer cannot access the server and enjoy services of a BSNL customer and vice versa. With this, it is quite understandable what a private server is.
Coming to Public Server, as the name suggests, these are available to everyone and are completely free of cost. It provides DNS resolution to anyone who requests it to them. These servers are utilized for faster and safer networking.

These are used as an alternative for Private DNS servers. The most basic examples are Google, Scrubit, and OpenDNS, all of which will be elucidated below.
One obvious advantage of a Public server over Private server is its universal access. You might have seen certain sites being blocked by servers and message ‘This website is not available in your country’ being displayed.
This is because the servers cannot link across long distances, due to which translation to the required IP address doesn’t occur, and the above message gets displayed.
But this can be resolved by changing the DNS server to the country where the page is accessible. But this cannot be done in Private servers due to it’s restriction to that organization localized in that area. Hence Public servers are at an insurmountable advantage Private servers.
