How to reset dns in cpanel server?

When we add a domain to cPanel, a standard set of DNS records is automatically created. If you add/delete DNS records and want to revert back to the original DNS, you can Reset the DNS Zone. This will remove all your custom DNS records and create the standard records for your domain. The instructions below provide the steps to reset your DNS zone file. 

1.Login into the cPanel
2.Click the Zone editor icon under the domains section
3.Find your domain in the list under the Domain heading. Under the Actions heading, click on the Manage link that corresponds with the DNS Zone you want to reset.
4.Click on the button, located on the far right, in the heading section.
5.Click Reset Zone from the drop-down menu.
6.A pop-up dialog box is displayed and asks “Are you sure you want to erase all entries and revert to the default state?” Click on the Continue button to confirm and proceed to reset the zone.
