In this article we will see what is DNS ,The importance of DNS & how to set your DNS to google DNS and how it affects your internet Speed.
For all the Geeks out there just go and set your DNS to google DNS 18.104.22.168 and 22.214.171.124 rest follow
So "what is DNS" ? & Also why is important ?
As show in the diagram the very moment you press enter after selecting the URL lets say for example http://www.winhotspot.com in any of your browser's like firefox / Chrome/IE etc.. ( I like firefox :) )
first and foremost thing your browser does is to send a DNS request asking the IP address of winhotspot website .
Why does DNS request need to be sent ?.
Good question , Lets say If I and you want to communicate the classical way (old postal way sending letters each other). Then you need my home address and lets say that you got it form your friend , now you will write your address on the back of letter and we can start communicating to each other.
So the friend is DNS server. Our internet communication happens over TCP/IP stack , So our computer/Mobile/IP devices.. need the IP address to communicate in internet world ,so every URL you entered will ask the IP address to DNS.
Yes in IP packet we have source address like the classical way (write from address on the back of the letter ) so that the receiver can get back to the PC/device just sent the message.
In a sense it's asking what's the IP address for the URL www.winhotspot.com ?.
So we all got the gyan of DNS :) , Now we got the answer for our first question ie.. "what is DNS ?" and "why DNS is required ?"
How a good DNS gives a boost / increase your speed /response time ?
Most of you might have already got it why a good DNS increases you speed /Response time.
Back to old story , Lets say you have two friends .You ask your "friend 1" , "what's address of Harsha". Friend 1 replies I have kept it in home , I'll tell you tomorrow ( The slow , unintelligent DNS).
If your "friend 1" ask "friend 2" "Do you know the address of Harsha" (this is DNS request forwarding) , Then your second friend replies , yes Its #123,xyz.... (The Fast DNS)
So you are sitting in front of PC/mobile to load the content and most of the time the DNS will lead to delay.
How we can set the fastest DNS (google DNS) using winhotspot the "virtual wifi router" ?
The new explorer will open which contains the adapters as show in the image.
Now right click on the adapter which is connected to the internet (WAN) , In my case it connected to WAN/Internet via wireless adapter, so I will right click
2001:4860:4860::8844You can test your new DNS setting by using tracert command
you can check it by the command "tracert -d 126.96.36.199"
