  • Hidden Primary:

It is very similar to the primary-secondary DNS. The only difference between primary secondary and hidden DNS is that it will make it easy for the nameservers to take the action. When you enable this kind of secondary DNS, you will have to hide the primary DNS. After that, you will have to configure the records. These records will be sent to secondary DNS.
