One more thing. I'm now learning, quickly, about recent changes, such as the net-tools to iproute2 transition which, as I look at my other running systems, has been going for a while, and also learning more about the systemd changes. I will also add the Bios to UEFI transition, which the last two releases of Debian have been handling quite well.
So also thank you all, for the Network Lessons. Special thanks to Dan Ritter for Pasting examples of the ip command, of which email I had, frozen on my Android Phone, during a tense period of time during the procedure. In my opinion, "ip r" aces the route command. Kenneth Parker
