Google just introduced their own DNS service named "Google Public DNS", it's free and every one can use it. It's an interesting initiative from Google, as I can't seem to figure out that what kind of benefit Google intend to get from this free service at later stages. Few basic questions which come in mind about Google Public Domain Name Service (DNS) are, Why should one use it? What kind of benefits are associated with it? and How to use it?
Why to Use?
As per Google, the basic and primary motive behind introducing this free service is to make the web Faster and more Secure by providing end users with an alternative to their current DNS service and help in reducing load on ISP's DNS servers. Few lines from Google on this:
The average Internet user ends up performing hundreds of DNS lookups each day, and some complex pages require multiple DNS lookups before they start loading. This can slow down the browsing experience. Our research has shown that speed matters to Internet users, so over the past several months our engineers have been working to make improvements to our public DNS resolver to make users’ web-surfing experiences faster, safer and more reliable.
Google Public DNS is a recursive DNS resolver, similar to other publicly available services. We think it provides many benefits, including improved security, fast performance, and more valid results.
How to Use?
Setting/Implementing Google Public DNS is fairly simple, all you need to do is to go to your Local Area Network (LAN) or Wireless Network connection Properties and set the following Google Public DNS Primary/Secondary IP addresses:
