That's not nearly as simple as you now make it out to be.

You mean hijacking a legitimate domain name? Yea, I figured it would
take intent (and probably a fair amount of work) to do that. I don't
want to do that anyway. Sometimes you never know though technology is
getting rather plug-and-pray now days.

I don't fully understand how the "Global" domain systemworks...
perhaps another subject for me to add to the list of future reading.

There is the DNS-HOWTO which explains things. VERY BRIEFLY, you ask a
name server. If it doesn't know the answer, it asks one of the 'root'
servers ("what is the address of foo.bar.baz.example.com?"), who refers
it to a top-level domain server ("ask <mumble> who knows about .com").
The top-level domain server will refer it to a 'second level' domain
server ("ask <mumble.mumble> who knows about example.com"). This is
repeated as needed until your name server finds the server who knows
that "foo.bar.baz.example.com is 192.0.2.145".

If you have a bogus domain on your name server, it becomes a problem
for others IF they somehow get referred to your server to ask about
that domain. Not very likely. However, those who are using your
name server to ask DNS questions (which generally means those systems
on your LAN) get the "wrong" answer, and will not be able to reach the
"real" host (whether or not that is their intent).
