Description

The initial configuration approach for the DNS service specified a bind-address that designated the network interface to which the service should bind its listener port. However, there is a need to potentially specify multiple DNS service instances (HA approach) and therefore a need to specify bind addresses for each instance (and those interfaces may vary between hosts). This may take a for similar to the RM HA approach (rm1, rm2)
