I have a few computers at home. For each of the computers, I can see the internal home network ip address on any given device by typing in ifconfig in the terminal.

If the device is connected to the home network via ethernet connection or via the built-in wireless connections in laptops, the internal ip address for each of the devices seems to be 192.168.0.X.

However, when I connect one of the devices using an external usb modem wireless adapter, which connects to the home network through wireless, when I check the ip address via ifconfig, for some reason it gets assigned 192.168.42.X instead.

Why are the ethernet and build in wireless connections getting 192.168.0.X, but the external usb wireless adapter gets 192.168.42.X?

Most importantly, is it possible to force it to get an internal ip address of 192.168.0.X?
