This service is responsible for transforming your domain names into IP addresses so that the browser can read them and load the resources. You will very rarely need to restart this service manually, however, if you need to do that, WHM provides you with the option to do so. Usually, it requires a restart once changes have been made to its configuration files but most of the changes you perform from the WHM control panel itself will do that automatically.
To Restart the DNS Service Follow these Steps:
Step1: Log in to Whm
Step2: In the Search Field search for the Dns service and click on it.
Step3: Then Click on Yes
Hence The Dns Service is Restarted.
