The DNS Check in Pingdom Tools will check your DNS health and help you find errors, and verify that you domain name has been set up correctly.
The DNS check will automatically find out which DNS servers are used by the domain name you specify, then perform a number of tests on them to make sure that the domain name is properly set up and that those DNS servers are responding in a consistent and correct manner.
There is also a DNS troubleshooting guide to help you interpret the potential errors and status messages for your DNS check.
We hope you will find this test helpful. If you got any questions regarding the test you can read about it here, about the test.
Very briefly about the DNS
The Domain Name System (abbreviated DNS) is simply put like the phone book of the Internet. It helps us, the users, keep track of website names like pingdom.com or google.com, rather than having to remember the IP-address that the computer needs to start any form of communication.
The DNS lets you surf the Internet with your web browser using URLs, which are far more handy and easy to remember than IP-addresses, but it also helps our emails find their way to the proper recipients.
So in short, the DNS is absolutely essential for everyone using the Internet.
