Consider the following points when you plan your logical addresses:
Each data-service resource group that uses a logical address must have a hostname specified for each public network from which the logical address can be accessed.
The IP address must be on the same subnet as the test IP address that is used by the IP Network Multipathing group that hosts the logical address.
