Yes, the IPs used on the ExpressRoute connection are whatever is chosen for the internal IP scheme of the VPC. ExpressRoute is a VPN connection into that internal side of a VPC.  On our carrier (MegaPort), ExpressRoute looks similar to an Option A NNI connection. BGP is used for routing.

The source IPs on packets crossing out of the VPC onto the Azure-provided Internet may or may not be static, but internally they are usually static RFC 1918 addresses.

Weâ??ve been using ExpressRoute for our own office systems and a small handful of customers for about two years now. However, we donâ??t use diffserv on ExpressRoute, so canâ??t comment on that.
