Other than as a lookup table for the route command...

That is, I note that when I do route, it displays names for all the
"Destinations" except for one - that is, for the base of my local LAN (setup
with IP Masq).  That address is 192.168.0.0

If I edit /etc/networks and add a line like:

        LocalLAN        192.168.0.0

Then when I do route, it looks pretier.  But I am afraid to do this, because
I don't know what other scripts/programs may be accessing this file.

AFAIR, RedHat does use the networks file in its initialization scripts, but
I don't think that Debian does.  Are there any other side effects?

Actually, it is perfectly acceptable.

And if x=0, you get the above.  The network address is then
192.168.0.0.

No hostnames within that network should be 0 (or 255), though.  The
router, for one, should probably be 192.168.0.1.

And this was probably being even more picky.  Many people prefer using
the 192.168.1.0 network to avoid these confusions.  So be it.

BTW, A,B and C networks have been abolished years ago.
You can only tell the size of a network bij looking at its netmask.

It's just an alias file like /etc/hosts. Whatever other programs access the
file, they should all consider it an alias file and not expect anything else.

I've been build too many networks! Tor you're absolutely correct.
The 192.168.0.0 network entry is correct if your host address is
192.168.0.x (where x is 1 - 254). As a side issue an entry of
192.168.255.0 would be valid for a network whose host address is
192.168.255.x (where x is 1 - 254).
