Approaches are provided for managing scope of and access to network services. In one approach, a source device and a target device are each provisioned with a service connector that is configured to communicate with a service manager that executes on a device that is different than the source and target devices. Using its service connector, the source device is able to discover a network service hosted by the target device even though the source device and target device are in different subnets or networks. In another approach, a service manager limits which network services are visible to a source device even though the network services are hosted on target devices that are on the same subnet as the source device. In this approach, the source device uses a service connector to discover the service manager and receive a list of registered services hosted on one or more target devices.
