You are planning the IP addressing for the subnets in Azure virtual networks. Which type of resource requires IP addresses in the subnets?

Azure Virtual Network NAT provides outbound internet connectivity for a subnet by using public IP addresses, and while it's associated with a subnet, it does not consume private IP addresses from the subnet's range for its own operation.

Service endpoint policies are security features that define which specific Azure resources can access services over a service endpoint, and they do not consume IP addresses from subnets.

An internal load balancer (ILB) in Azure uses a private IP address for its frontend configuration to distribute incoming network traffic to its backend pool. This private IP address is allocated directly from the available IP addresses within the subnet where the ILB is deployed, thus consuming an IP from that subnet.

Virtual network peering is a logical connection between two virtual networks that enables communication between them and does not consume IP addresses from the subnets involved.
