 ## Conceptual overview
 
 A private endpoint is a special network interface for an Azure service in your [Virtual Network](../virtual-network/virtual-networks-overview.md) (VNet). When you create a private endpoint for your App Configuration store, it provides secure connectivity between clients on your VNet and your configuration store. The private endpoint is assigned an IP address from the IP address range of your VNet. The connection between the private endpoint and the configuration store uses a secure private link.
