US Patent 9207963 Preventing cloud cartography

Technologies are presented for a network/hypervisor approach to maintain a stable and separate network address for the hypervisor on a multi-tenant system and changeable network addresses for the virtual machines (VMs). In some examples, the VM addresses may be decoupled from the domain address for the hypervisor so they can be changed arbitrarily and independently without impacting command messaging, and the domain address for the hypervisor may not form a part of the delivery chain for messages to the VMs. The system may also consume only the same number of IP addresses as currently used.
