"internal" means behind the firewall (which everything is,
transparently). We don't NAT because we don't have to .. the 1918 space
is used for stuff we don't want to be routable (like thermostats).

Correct. When you request a DNS entry, there's a little box on the
webform that says "external?" .. and if you check it, the same entry
gets put in the outward-facing DNS (both A and PTR). Otherwise it stays
the default csu-x-x-x-x.csuohio.edu, regardless of what it is on the inside.
