+### Multiple address prefixes on a subnet
+
+Multiple address prefixes on a subnet is a feature that offers the ability to modify IP address spaces on a subnet. With this solution, customers using virtual machines and virtual machine scale sets can add and remove IP address prefixes to meet their scaling requirements.
+
+**Limitations**: 
+
+- Customers can only use a single customer address (CA) configuration per NIC
+
+- Customers can only use on VM and VMSS subnets. Delegated subnets aren't supported.
+
+Pricing: this virtual network feature is offered free of charge.
+
+We welcome you to share your feedback about this feature in this [quick survey](https://aka.ms/multiple-prefixes-feedback).  
+
+> [!IMPORTANT]
+> Multiple prefix support for Azure Virtual Network subnets is currently in public preview.
+> This preview version is provided without a service level agreement, and it's not recommended for production workloads. Certain features might not be supported or might have constrained capabilities. 
+> For more information, see [Supplemental Terms of Use for Microsoft Azure Previews](https://azure.microsoft.com/support/legal/preview-supplemental-terms/).

 ## Network security groups
 
 A [network security group (NSG)](../virtual-network/network-security-groups-overview.md) contains a list of Access Control List (ACL) rules that allow or deny network traffic to subnets, NICs, or both. NSGs can be associated with either subnets or individual NICs connected to a subnet. When an NSG is associated with a subnet, the ACL rules apply to all the VMs in that subnet. Traffic to an individual NIC can be restricted by associating an NSG directly to a NIC.
