Specifying a virtual name server as a secondary 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:

  1. Stop the Domain Name Server.

  2. In the shortcuts section of the Home page, click Configuration (DNS section).

  3. In the Configuration: Name Servers form, locate Virtual DNS and in the Actions column, click Edit.

  4. In the Secondary Server/Virtual DNS Setting form, click the Virtual DNS option.

  5. In the Server Name field, enter the fully qualified name of the DNS server you want to use as the virtual secondary name server.

  6. In the IP Address field, enter the IP address of the virtual secondary DNS server.

  7. Click Save.

  8. Restart the Domain Name Server.

  9. 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.
