Google Public DNS
Google Public DNS is a free DNS (Domain Name System) service announced on 3 December 2009 as part of Google’s effort to make the web faster.
DNS means Domain Name System which translates the URL typed into corresponding server’s IP.For example when you type www.google.com in the browser what essentially happens is that the DNS searches the list of IP’s and finds out the Google server’s IP and displays the page.
Why it is Important?
The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.
How to change the DNS servers?
Configure your network settings to use the IP addresses 126.96.36.199 and 188.8.131.52 as your DNS servers.To know more about configuring click here.
