Testing the Settings:
1) Type the hostname (http://www.google.com) in your browser. If it resolves correctly, bookmark this page. Access the page from bookmark. If both tests work, everything is working fine.
2) If it is not working, type a fixed IP address in your browser. If it resolves correctly, bookmark the page. Access the page from bookmark. If both tests work, there is a problem with your DNS configuration.
3) Roll back the changes which you have done and test it again. If it failed again, contact your ISP or Network Administrator.
That is how we can configure network settings to use Google public DNS.
