In 30 years I've never seen an isolated network. May I ask how this
might be done?
An alternative example (with no Wi-Fi):
* One switch or hub. Connect to power.
* Two or more computers. Connect to the switch/hub, and to power.
* On each computer, set an appropriate address manually, so they can
talk to each other.
Use any non-routable IP addressing you like. 192.168.1.* is a common
choice.
OK, this I can understand and do. I had actually typed up this as a "guess", but then erased it thinking it might need something more complicated.
As an even simpler example, if you only have *two* computers, you can
connect them directly to each other, without needing a switch/hub.
Back in the olden days (before gigabit ethernet adapters), you would
have needed a special crossover ethernet cable for this. Now, on modern
devices, you should be able to use a regular ethernet cable.
I have an extra switch siting on the shelf, so I'm good.
Thanks to all for the continuing help.
