 # Configure an application gateway with an internal load balancer (ILB) endpoint
 
-Azure Application Gateway can be configured with an Internet-facing VIP or with an internal endpoint that is not exposed to the Internet (by using a private IP for the frontend IP address), also known as an internal load balancer (ILB) endpoint. Configuring the gateway using a frontend private IP address is useful for internal line-of-business applications that are not exposed to the Internet. It's also useful for services and tiers within a multi-tier application that sit in a security boundary that is not exposed to the Internet but still require round-robin load distribution, session stickiness, or Secure Sockets Layer (SSL) termination.

 ## Create an application gateway
 
-For Azure to communicate between the resources that you create, it needs a virtual network. You can either create a new virtual network or use an existing one. In this example, we will create a new virtual network. You can create a virtual network at the same time that you create the application gateway. Application Gateway instances are created in separate subnets. You create two subnets in this example: one for the application gateway, and another for the backend servers.

+8. For **Frontend IP address type**, select **Private**.
+
+   By default, it's a dynamic IP address assignment. The first available address of the configured subnet is assigned as the frontend IP address.
    > [!NOTE]
    > Once allocated, the IP address type (static or dynamic) cannot be changed later.

 ## Add backend pool
 
-The backend pool is used to route requests to the backend servers which will be serving the request. Backend can be composed of NICs, virtual machine scale sets, public IPs, internal IPs, fully qualified domain names (FQDN), and multi-tenant back-ends like Azure App Service. In this example, we will use virtual machines as the target backend. We can either use existing virtual machines or create new ones. In this example, we will create two virtual machines that Azure uses as backend servers for the application gateway. To do this, we will:
