Sometimes using public dns servers for resolving dns queries can get you better browsing experience. Well I am not saying that public dns servers like google dns, ultra dns or open dns are faster than your local/isp's dns servers. But sometimes public dns servers can give you better Internet experience if properly used along with your isp's dns server. If you want the fastest dns query results then it is suggested to setup your own dns server on your network.

In my case I was facing slow Internet browsing when my isp's dns server is overloaded with dns query requests on pick hours. So I started to use google public dns along with my isp's dns and dramatically my problem got solved.

So whenever my isp's dns is overloaded, takes more time to resolve dns query or is unable to resolve any query its just automatically switch to google dns. By using this method I got 20% better browsing speed.

You can use any other public dns service like google dns,open dns or ultra dns. But I will suggest to use google dns because it doesn't display ads and remove logged user information after 24 hrs. You can better see the privacy policy of google dns. To know performance benefits click here

To use google dns along with with current dns first you have to know your current dns server's address.
I am assuming that you are using DHCP for your current connection.
To know your current dns server's address just go to command prompt on windows

Type ipconfig /all
press enter
this will display all information about your current network configuration.
Look for the DNS Servers



take note of the dns server address.

now go to "Network Connections" from Control Panel then to Properties of your current network adapter you are using to connect the internet.



then open the Propertise page selecting TCP/IPv4 protocol .
then configure like below



select Use the following DNS server address
then on Preferred DNS server type your current dns server address. (Here in my case 192.168.1.1 will be preferred dns as i am using a router)

then on Alternate DNS server type the address of google dns 8.8.8.8 (if you want use any other provider type that dns service provider address here)

click OK close all windows. Now Enjoy better browsing speed. :D

If you are on Ubuntu or any other Debian based OS then go to Network Manager/Network Connections applet and select your Current Network adapter (Connection name) that you are using connect internet . Edit settings of TCP/IPv4. Select method Automatic (DHCP) Address only like below (if using Point-to-Point Protocol then select Auto PPP Address only)



Type dns server addresses separated by commas on DNS Servers Text Box. Apply the new settings and enjoy :D
to know the dns server address on ubuntu open Terminal
type: cat /etc/resolv.conf
hit return
take note of the addresses

you can do the same editing /etc/resolv.conf and adding the nameservers.
