I have a domain called "example.com" and it is already serving DNS on "Server A" using ns1.example and ns2.example.com
Is it possible to create a separate DNS server using "example.com" on "Server B" using ns20.example.com and ns21.example.com? Keep in mind I don't want those servers to be slaves, they would have different zone files.
Is this possible without touching the DNS on Server A?
Any solutions/scenarios of making this work would be appreciated.
