Manually provision IP address pools as part of an Azure VM scale set

Configure IP Pools for each member of the VM scale set during provisioning by associating multiple ipConfigurations with the scale set’s networkInterfaceConfigurations.

The following example networkProfile configuration for an ARM template configures pools of 32 IP addresses for each VM in the VM scale set.

"networkProfile": {
  "networkInterfaceConfigurations": [
    {
      "name": "[variables('nicName')]",
      "properties": {
        "ipConfigurations": [
          {
            "name": "[variables('ipConfigName1')]",

              "primary": "true",
              "subnet": {
                "id": "[concat('/subscriptions/', subscription().subscriptionId,'/resourceGroups/', resourceGroup().name, '/providers/Microsoft.Network/virtualNetworks/', variables('virtualNetworkName'), '/subnets/', variables('subnetName'))]"
              },
              "loadBalancerBackendAddressPools": [
                {

                }
              ],
              "loadBalancerInboundNatPools": [
                {

                }
              ]
            }

              }
            }
          }
          .
          .
          .

              }
            }
