Express route provides a private connection between on premise data center and Azure. Since traffic does not go over the Internet, why is a public address needed for the Express Route Gateway? I would expect the Express Route Gateway to use an IP address from the private IP address space from the VNet.

Azure ExpressRoute
Azure ExpressRoute

An Azure service that provides private connections between Azure datacenters and infrastructure, either on premises or in a colocation environment.

    Hello @Tyrone Paige ,

    As per the FAQ documentation here The public IP address associated with Express Route Gateway is used for internal management only, and does not constitute a security exposure of your virtual network.

    Hope this helps!
