When planning IP addressing for Azure virtual network subnets, which resource type requires IP addresses assigned from the subnet?

Internal Load Balancers (ILBs) require IP addresses assigned from a subnet because they distribute incoming network traffic to virtual machines within that virtual network. The ILB's frontend IP configuration, which clients connect to, must be an IP address from one of the subnets within the virtual network. Storage accounts are PaaS services and do not directly consume IP addresses from your subnets for their primary access. Service endpoints extend your virtual network's identity to Azure services over the Azure backbone, but they don't assign IP addresses from your subnet to the service itself. Service endpoint policies allow you to filter traffic to Azure services over service endpoints, also not consuming subnet IP addresses.
