A method and a system for determining a path of data traffic based on a destination Internet Protocol (IP) address, the destination IP address being either private or public and belonging to any one of multiple organizations. In the method and system, a subscribed device identifier and the destination IP address of one of the multiple organizations is received at a managed service platform. If both the subscribed device identifier and the destination IP address of the one of the multiple organizations are not registered in a predetermined policy database, a subscriber or an owner of the subscribed device is prompted, at a telecommunications endpoint associated with the subscribed device identifier, to register the endpoint. The subscribed device identifier is then registered in the predetermined policy database, based on information received from the telecommunications endpoint in response to the prompting. If the subscribed device identifier and the destination IP address of the one of the multiple organizations are registered in the predetermined policy database, a service device of the managed service platform on a private network routes the data traffic to a private network resource of the one of the multiple organizations. If the subscribed device identifier is registered in the policy database and the destination IP address of the one of the multiple organizations is not registered in the predetermined policy database, the service device of the managed service platform on the private network routes the data traffic via an IP transit service to the public Internet.
