If the domains are hosted on a server farm comprising many Parallels Pro Control Panel servers and other business servers, it may be more efficient from an organizational point of view, to have all the zones created on one single central server in the farm, regardless of which Parallels Pro Control Panel server hosts the domain. In this scenario, you may want to nominate one server, for example nameserver.isp.net as the master name server and set any Parallels Pro Control Panel server, for example s1.isp.net on which you are creating a domain, as the slave server that obtains updates from the master server.
Parallels Pro Control Panel will create a slave zone on the Parallels Pro Control Panel server s1.isp.net and configure it to obtain updates from the master server nameserver.isp.net.
Important: Before you create the domain, you must create the zone on the master server nameserver.isp.net, otherwise Parallels Pro Control Panel will not be able to add the required records inside the master zone. Further, the master server must be configured to allow the slave s1.isp.net to obtain updates from the master. If you want Parallels Pro Control Panel to add records to this zone, you must also allow s1.isp.net to update the zone that resides on nameserver.isp.net.
Assuming that you want to configure an external server nameserver.isp.net as the master name server and the Parallels Pro Control Panel server s1.isp.net as the slave name server for a domain named myfirstcustomer.com, perform the following steps:
Note: The external server can be any server running an implementation of the DNS protocol and must be added as an external DNS server in Parallels Pro Control Panel. Contact your service provider to ensure that the server is added as an external server.
Parallels Pro Control Panel automatically creates the slave zone myfirstcustomer.com and zone records for the domain. To verify, click Zones (DNS) in the shortcuts section of the Home page.
