Brian,
Thank you for still being around.
Yes, I understand everything you said.
I will again visit your shares, print/save what ever I need and move forward.
Slowly.
I suppose that the reason I raised my ask initially was to find out why so many
of our Collective have poo-poo's about using the 10.x.x.x series.
I know that it is a huge (full) range.
But,
When I use it I always use a sub-net mask of 255.255.255.0.
I am still grappling with the the sub-net part. My problem!
Perhaps this is my own stupidity. Sorry List (what's left of it!) Apologize completely.
There should be "quiet" from me in the next few days as my LAN shakes out.
Thank you.
Duncan

It doesn't matter one bit.  192.x.x.x and 10.x.x.x are private only that
they are non-routable address ranges.  That means by design, any packet with
a 10 or 192 header dropped on the internet will go nowhere.  Which is why
everyone can use them in their internal LAN without needing to reserve
unique ranges.  It also makes for great security, because in the event that
some of your internal LAN traffic does get on the net nobody can do anything
with it.

So changing from 192 to 10 ranges is really only cosmetic.  But if you are
intent on doing it, it shouldn't be too hard.  If you are using your router
as a DHCP server, then you should be able to change this fairly simply.
Somewhere in the router settings should be the ability to specifcy what
address range the router gives out.  Not all routers wil probably support
this, but I think most will.

If your router doesn't support it, or if you are using static IPs, then just
go to each machine and give it a unique 10.x.x.x address.  But make sure you
get them all, otherwise anything left on the old 192 range won't be ablet to
communicate.
