I just meant that they should work fine in your LAN (Local Area Network).

You can plug all computers into the same switch, and you generally must get
IP addresses assigned by the same router.  So what you have should work
fine.  Win-test sends "broadcast" packets (UDP) to every computer connected
in your LAN, but only the computers running Win-Test will look at them; the
rest of the computers will ignore them, and you should notice no impact on
your network at all.

The easiest thing to do is open a Windows command prompt (Start, Run,
CMD.EXE), and in the command prompt window, type IPCONFIG [Enter].   This
will display the "IPV4 address" of the machine, e.g. 192.168.0.2.  If the
two machines only differ in the 4th number (e.g. 192.168.0.10 and
192.168.0.15), then they are on the same "subnet" and the broadcast system
will work fine.  But you still have to click that "By default" button in
Win-Test on both computers so that both use the same broadcast address.

If the two IP addresses are more different, e.g. 192.168.0.10 and
192.168.1.11, then things get more complicated.

Thank you – that is very helpful!  I assume that if for some reason the two

Don't manually change any addresses.  Each computer will have a unique IP
address already.  Chances are very high that clicking the "By default"
button on both will be all the setup you need to do.  Just do that, keep
Win-Test running on both, type Alt-G (gab), and whatever message you type
should show up on the other computer, and vice versa.   Then you know your
network is set up correctly.
