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.
