 Virtual machines (VMs) in Azure can have multiple virtual network interface cards (NICs) attached to them. A common scenario is to have different subnets for front-end and back-end connectivity. You can associate multiple NICs on a VM to multiple subnets, but those subnets must all reside in the same virtual network (vNet). This article details how to create a VM that has multiple NICs attached to it. You also learn how to add or remove NICs from an existing VM. Different [VM sizes](../sizes.md) support a varying number of NICs, so size your VM accordingly.
 
+> [!NOTE]
+> If multiple subnets are not required for a scenario, it may me more straightforward to utilize multiple IP configurations on a single NIC.  Instructions for this setup can be found [here](../../virtual-network/ip-services/virtual-network-multiple-ip-addresses-portal.md).

 ## Prerequisites
 
 In the following examples, replace example parameter names with your own values. Example parameter names include *myResourceGroup*, *myVnet*, and *myVM*.

-Learn about a public IP address prefix. A public IP address prefix is a contiguous range of standard SKU public IP addresses.  When you create a public IP address resource, you can assign a static public IP from the prefix and associate the address to Azure resources. For more information, see [Public IP address prefix overview](public-ip-address-prefix.md).

-Learn how to add, change, and remove public and private IP addresses for a network interface. Private IP addresses assigned to a network interface enable a virtual machine to communicate with other resources in an Azure virtual network and connected networks. A private IP address also enables outbound communication to the Internet using an unpredictable IP address. A [Public IP address](virtual-network-public-ip-address.md) assigned to a network interface enables inbound communication to a virtual machine from the Internet. The address also enables outbound communication from the virtual machine to the Internet using a predictable IP address. For details, see [Understanding outbound connections in Azure](../../load-balancer/load-balancer-outbound-connections.md?toc=%2fazure%2fvirtual-network%2ftoc.json).
+Both Private and Public IP addresses can be assigned to a virtual machine's network interface controller (NIC).  Private IP addresses assigned to a network interface enable a virtual machine to communicate with other resources in an Azure virtual network and connected networks.
