DNS Redirection for Cross-Network Failover

When the two systems to be clustered are in two different network segment, the common configuration of local host table or IP address for clustering failover may not work because neither the cluster name nor the cluster IP can be used for public connection in a different network segment. In this situation, DNS setup is employed to overcome the difficulty. 

You can use DNS to redirect client network traffic to the secondary server when primary system fails.  DNS entry will be updated automatically  to reflect the changes in cluster role.  DNS servers have be able to accept dynamic DNS entry update for failover to function correctly.
