1. A communication apparatus operable selectively in a power-saving state or in a normal state in which more power is consumed than in the power-saving state, the communication apparatus comprising a controller configured to:
receive, in an operation state of the communication apparatus being the power-saving state, a request signal from an external device, the request signal including a source IP address being an IP address of the external device;
switch the operation state of the communication apparatus from the power-saving state to the normal state in response to the request signal including the source IP address being a global IP address, the operation state of the communication apparatus being not switched from the power-saving state to the normal state in response to the request signal including the source IP address being a private IP address;
perform a predetermined process in response to the operation state of the communication apparatus being switched from the power-saving state to the normal state, the predetermined process being not performed in response to the operation state of the communication apparatus being the power-saving state; and
transmit, to the external device, a first response signal to the request signal without the operation state of the communication apparatus being switched from the power-saving state to the normal state in response to the request signal including the source IP address being a private IP address.
