Specifying a virtual name server as a slave server

If you are using Ensim Pro as a DNS server, you can create a virtual name server to act as a slave 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 master name server. Since the IP address of the virtual slave server maps to the master server, if the master server stops operating, the slave server will as well.

To specify a virtual slave name server:

1. Stop the Domain Name Server.

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

3. Locate Virtual DNS Server in the server list and in the Actions column, click . The Virtual DNS Setting form opens.

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

5. In the Virtual DNS Server IP Address field, enter the IP address of the virtual slave DNS server.

6. Click Update.

7. Restart the Domain Name Server.

8. 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.
