These parameters (located in Service Plans > select a plan > DNS tab) define how the DNS service running on the Plesk-managed server will serve DNS zones for websites hosted on the plan.



A master or primary name server stores locally the zone file it serves, while a secondary server only retrieves a copy of this file from the primary.


A slave or secondary server retrieves a copy of the zone file from the primary name server.
