The server can store first address information specifying at least one first global IP address and is configured to: receive, from the client device, an IP packet containing first information and a second global IP address; determine whether the second global IP address coincides with the specified first global IP address; and when the second global IP address coincides with the specified first global IP address, transmit second information to the client device. The client device stores an object program and is configured to: transmit the first information to the server when the client device is in a restricted state in which the client device is not permitted to execute the object program; receive the second information from the server; and cancel the restricted state of the client device when the second controller receives the second information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system, server, and client device","description":"A communication system includes: a client device and a server.
