As a user you always look for ways to get the best internet speed. I remember doing it when my internet speed was 64Kbps and still look forward to do it at 5Mbps. You cannot change the speed that ISP provides, but you can make settings to get the best from it. Your internet speed depends on many factors. DNS (Domain Name System) is one such factor that helps improve internet speed.
What is DNS?
DNS can be explained as a phone book that saves names against phone numbers. It is difficult to remember phone numbers of friends however close they may be to you. On the other hand you are familiar with their names. So you store their phone numbers against their names so that you don’t need to remember the phone numbers.
DNS is a kind of internet address book that saves the ip address of the websites against their name. It is like you can remember the name of the website but remembering the ip address is difficult. Thus DNS facilitates viewing websites.
Technically speaking, it translates easily memorized domain names to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide. The Domain Name System is an essential component of the functionality of the Internet.
Default, Public and Open DNS:
Your ISP (Internet Service Provider) provides you default DNS. These DNS does the required translation for you while browsing internet. However a good DNS would mean a better browsing experience.
Other free and paid DNS services are also available to provide you the fastest DNS severs.
Finding the Best DNS:
Google has a tool called Namebench that queries the internet based on your browser history using your default DNS and compares the result with other available DNS.
I checked it with my Default DNS.
The results showed that my default DNS is the fastest.
To verify it again I used the Google DNS and 18.104.22.168 (incorrect DNS) as Name servers. The result was the same, but this time it said the MTNL, Mumbai DNS was the Fastest.
In short this small tool looks for the best available DNS setting for your network.
It generates a detailed report about the best DNS settings, the results obtained using various DNS and recommends the Fastest DNS.
