Communication Device

A communication device comprising:

• a first interface configured to perform communication using a first network;
• a second interface configured to perform communication using a second network;
• a processor;
• and
• a memory storing first device information for identifying the communication device in the first network, second device information for identifying the communication device in the second network, and instructions that, when executed by the processor, cause the communication device to perform;
• generating a first server certificate including the first device information as owner information and a second server certificate including the second device information as the owner information;
• receiving a communication request which requests execution of target communication with the communication device, the target communication using a server certificate;
• determining whether the communication request is a first communication request received from a first specific device belonging to the first network through the first interface or a second communication request received from a second specific device belonging to the second network through the second interface;
• executing target communication with the first specific device through the first interface by using the first server certificate in a case where the first communication request is received from the first specific device;
• and
• executing target communication with the second specific device through the second interface by using the second server certificate in a case where the second communication request is received from the second specific device.
