Specifying a virtual name server as a secondary server
Note: If your domain name registrar or service provider maintains your domain information on their DNS servers, you do not need to do anything with the DNS settings of Ensim Pro; the settings shown in the DNS section of the Server Administrator GUI are not used. For more information, see: Introduction to DNS and name servers Using Ensim Pro as a DNS server
If you are using Ensim Pro as a DNS server, you can create a virtual name server to act as a secondary DNS name server. This satisfies the requirement that you must have two DNS name servers to create a domain.
Be aware that creating a virtual name server does not actually provide redundancy because you are requesting Ensim Pro to add a second IP address to the specified primary name server. Since the IP address of the virtual secondary server maps to the primary server, if the primary server stops operating, the secondary server will as well.
To ensure redundancy, you can specify a secondary server with its own IP address.
To specify a virtual secondary name server:
Stop the Domain Name Server.
In the shortcuts section of the Home page, click Name Servers (DNS section).
Locate Virtual DNS Server in the server list and in the Actions column, click . The Virtual DNS Setting form opens.
In the Virtual DNS Server Name field, enter the fully qualified name of the DNS server you want to use as the virtual secondary name server.
In the Virtual DNS Server IP Address field, enter the IP address of the virtual secondary DNS server.
Click Update.
Restart the Domain Name Server.
Note: After making changes to the domain name server, you must restart the name server for your changes to take effect. Be aware that it may take up to 48 hours for your DNS changes to be visible on the Internet. However, if you are not using Ensim Pro as a DNS server, these settings are not used.
