 # Assign multiple IP addresses to virtual machines using the Azure portal
 
-[!INCLUDE [virtual-network-multiple-ip-addresses-intro.md](../../../includes/virtual-network-multiple-ip-addresses-intro.md)]
+An Azure Virtual Machine (VM) has one or more network interfaces (NIC) attached to it. Any NIC can have one or more static or dynamic public and private IP addresses assigned to it. 
 
-This article explains how to create a virtual machine (VM) through the Azure Resource Manager deployment model using the Azure portal. Multiple IP addresses cannot be assigned to resources created through the classic deployment model. To learn more about Azure deployment models, read the [Understand deployment models](../../azure-resource-manager/management/deployment-models.md) article.
+Assigning multiple IP addresses to a VM enables the following capabilities:
 
-[!INCLUDE [virtual-network-multiple-ip-addresses-scenario.md](../../../includes/virtual-network-multiple-ip-addresses-scenario.md)]
+* Hosting multiple websites or services with different IP addresses and TLS/SSL certificates on a single server.
 
-## <a name = "create"></a>Create a VM with multiple IP addresses
+* Serve as a network virtual appliance, such as a firewall or load balancer.
 
-If you want to create a VM with multiple IP addresses, or a static private IP address, you must create it using PowerShell or the Azure CLI. To learn how, click the PowerShell or CLI options at the top of this article. You can create a VM with a single dynamic private IP address and (optionally) a single public IP address. Use the portal by following the steps in the [Create a Windows VM](../../virtual-machines/windows/quick-create-portal.md) or [Create a Linux VM](../../virtual-machines/linux/quick-create-portal.md) articles. After you create the VM, you can change the IP address type from dynamic to static and add additional IP addresses using the portal by following steps in the [Add IP addresses to a VM](#add) section of this article.
+* The ability to add any of the private IP addresses for any of the NICs to an Azure Load Balancer back-end pool. In the past, only the primary IP address for the primary NIC could be added to a back-end pool. For more information about load balancing multiple IP configurations, see [Load balancing multiple IP configurations](../../load-balancer/load-balancer-multiple-ip.md?toc=%2fazure%2fvirtual-network%2ftoc.json).
 
-## <a name="add"></a>Add IP addresses to a VM
+Every NIC attached to a VM has one or more IP configurations associated to it. Each configuration is assigned one static or dynamic private IP address. Each configuration may also have one public IP address resource associated to it. To learn more about IP addresses in Azure, read the [IP addresses in Azure](../../virtual-network/ip-services/public-ip-addresses.md) article.
 
-You can add private and public IP addresses to an Azure network interface by completing the steps that follow. The examples in the following sections assume that you already have a VM with the three IP configurations described in the [scenario](#scenario), but it's not required.
+> [!NOTE]
+> All IP configurations on a single NIC must be associated to the same subnet.  If multiple IPs on different subnets are desired, multiple NICs on a VM can be used.  To learn more about multiple NICs on a VM in Azure, read the [Create VM with Multiple NICs](../../virtual-machines/windows/multiple-nics.md) article.
+
+There's a limit to how many private IP addresses can be assigned to a NIC. There's also a limit to how many public IP addresses that can be used in an Azure subscription. See the [Azure limits](../../azure-resource-manager/management/azure-subscription-service-limits.md?toc=%2fazure%2fvirtual-network%2ftoc.json#azure-resource-manager-virtual-networking-limits) article for details.
+
+This article explains how to add multiple IP addresses to a virtual machine using the Azure portal. 
+
+> [!NOTE]
+> If you want to create a virtual machine with multiple IP addresses, or a static private IP address, you must create it using [PowerShell](virtual-network-multiple-ip-addresses-portal.md) or the [Azure CLI](virtual-network-multiple-ip-addresses-cli.md). 
+
+## Prerequisites
+
+- An Azure account with an active subscription. [Create an account for free](https://azure.microsoft.com/free/?WT.mc_id=A261C142F).
+
+- An existing Azure virtual machine. For more information about creating a virtual machine, see [Create a Windows VM](../../virtual-machines/windows/quick-create-portal.md) or [Create a Linux VM](../../virtual-machines/linux/quick-create-portal.md). 
+    
+    - The example used in this article is named **myVM**. Replace this value with your virtual machine name.
+
+> [!NOTE]
+> Though the steps in this article assigns all IP configurations to a single NIC, you can also assign multiple IP configurations to any NIC in a multi-NIC VM. To learn how to create a VM with multiple NICs, see [Create a VM with multiple NICs](../../virtual-machines/windows/multiple-nics.md).
