Abstract:
A communication device may: receive a request signal from an external device via a communication interface, the request signal including a first IP address of the external device as a sender address; determine whether the first IP address in the request signal is a global IP address in a case where the request signal is received from the external device; and send a response signal to the request signal to the external device in a case where it is determined that the first IP address is not the global IP address, wherein sending of the request signal is restricted in a case where it is determined that the first IP address is the global IP address.
