The Primary and Secondary DNS servers are configured in the Node Level Settings. For more information, see Configuring Host Information and DNS.

A Domain Specific DNS Server is configured through the Split-DNS settings. The following section describes how to configure the Split-DNS.

The Split-DNS can also be configured using DHCP on the Logical Interface. For more information, see Configuring and Modifying Logical Interfaces .

Create Split-DNS Entry - Field Definitions

DNS Server IP

The DNS Server IP is the IP address that can resolve names configured to the specified Domain Name attribute. Valid entry: IP address (IPv4 or IPv6).

A DNS server may be associated with many domain names. One entry should be configured for each DNS server and domain combination.

When a domain-specific DNS server fails, it fails over to the next domain-specific DNS server associated with that domain.  Global DNS servers are not used for a domain, even if all of the configured domain-specific DNS servers fail.

Domain Name

Name of the specified domain to be used for Split DNS. Valid entry: maximum of 255 characters.

One entry should be configured for each domain and DNS server combination.
