Automatically change the IP address of the osc_server domain name in the hosts file AHK script.
Thank you, @Greenman (for the hosts idea) and @GeneralMidi (for the AHK OSC integration DLL link - posted here)

Now, if I connect my O-S-C server device and my client device to another router, all I have to do is run the script, and my bookmark (http://osc_server:8080) will be automatically linked to the correct IP.
Hurray! :partying_face:
