Communication device, and non-transitory computer-readable recording medium storing computer-readable instructions for communication device

A communication device, comprising:

• a controller;
• and
• a memory configured to, in a case where the communication device belongs to a specific subnetwork among a plurality of subnetworks constituting a local area network, store network information capable of specifying a network address of the specific subnetwork,
• wherein the controller is configured to:
• specify, by sending a search signal to outside, a plurality of external devices, each of which belongs to the specific subnetwork or one or more other subnetworks different from the specific subnetwork in the plurality of subnetworks;
• specify from among the plurality of external devices, by using the network information in the memory, one or more first-type external devices belonging to the specific subnetwork and one or more second-type external devices belonging to the one or more other subnetworks;
• display a search result screen on a display, the search result screen indicating the one or more first-type external devices and the one or more second-type external devices in a distinguishable form by which the one or more first-type external devices and the one or more second-type external devices are distinguishable;
• and
• in a case where a specific external device is selected on the search result screen, perform a filter process related to whether to allow communication with the specific external device.

A non-transitory computer-readable storage medium storing computer-readable instructions for a communication device, wherein the communication device comprises:

• a processer;
• and
• a memory configured to, in a case where the communication device belongs to a specific subnetwork among a plurality of subnetworks constituting a local area network, store network information capable of specifying a network address of the specific subnetwork,
• the computer-readable instructions, when executed by the processor of the communication device, cause the communication device to:
• display a first selection screen on a display, the first selection screen being for selecting whether to search for, one or more first-type external devices belonging to the specific subnetwork or for one or more second-type external devices belonging to a subnetwork different from the specific subnetwork in the plurality of subnetworks;
• in a case where it is selected on the first selection screen by a user that the one or more first-type external devices are to be searched for, specify the one or more first-type external devices by using the network information in the memory and also by sending a search signal to outside;
• in a case where the one or more first-type external devices are specified, display a first search result screen indicating the one or more first-type external devices on the display;
• in a case where it is selected on the first selection screen by the user that the one or more second-type external devices are to be searched for, specify the one or more second-type external devices by sending a search signal to outside;
• in a case where the one or more second-type external devices are specified, display a second search result screen indicating the one or more second-type external devices on the display;
• and
• in a case where a specific external device is selected on the first search result screen or the second search result screen, perform a filter process related to whether to allow communication with the specific external device.
