The problem comes in when some config isn't right and the private
address escapes its bounds. Suppose I am using 0 (ok, I am, I should
change it sometime after I move back home). Suppose also that I put
the wrong interface in my DDTS config (I did that too, oops). Now
when you do a DNS query for 'dman2.ddts.net' you end up getting back
192.168.0.1. Your machine sees that, it's a valid address, and points
to some.host on your lan. That isn't a good thing.

Now that I know why it's a good idea not to use the same block as
everyone else, I will do that next time it is in my power/control to
choose the numbering.

Failure is not an option. It is bundled with the software.
