   I don't want "FAIL-over" - I want two or more
   subnets to be "live" ... access machines/devices
   on several subnets just by supplying the correct
   dot address or such.

   Preferably some fix that does NOT require 9999
   line scripts or $500 hardware.

   Not TOO long ago, we'd have asked why anyone
   would need more than 254 IP addresses easily
   in grasp. However that was before MANY boxes,
   MANY servers and finally "IOT".

   I did TRY to do this fix using a software router
   a few years back. Despite promises it didn't
   work right at all.

   Even now retired, my home has a lot of "IOT"
   type devices. It's beginning to get cluttered
   and ugly. I'd rather most of them be on another
   subnet entirely. Medium-sized biz, they're
   gonna be even MORE pressed to fit everything
   into just one subnet.
