 ## Considerations
 * The wizard for creating a new subnet defaults to a /24 network mask, which provides for 251 available IP addresses. Using a /28 network mask, which provides for 16 usable IP addresses, is sufficient for the service.
 * In each Azure Virtual Network (VNet), only one subnet can be delegated to Azure NetApp Files.   
-   Azure enables you to create multiple delegated subnets in a VNet.  However, any attempts to create a new volume will fail if you use more than one delegated subnet.
+   Azure enables you to create multiple delegated subnets in a VNet.  However, any attempts to create a new volume will fail if you use more than one delegated subnet.  
+   You can have only a single delegated subnet in a VNet. A NetApp account can deploy volumes into multiple VNets, each having its own delegated subnet.  
 * You cannot designate a network security group or service endpoint in the delegated subnet. Doing so causes the subnet delegation to fail.
 * Access to a volume from a globally peered virtual network is not currently supported.
 * Creating [user-defined custom routes](https://docs.microsoft.com/azure/virtual-network/virtual-networks-udr-overview#custom-routes) on VM subnets with address prefix (destination) to a subnet delegated to Azure NetApp Files is unsupported. Doing so will impact VM connectivity.
