Thanks for the clarification, Kevin.

Another good point. In our hosting business we initially set rDNS for 
all IP#s pointing to a given server for that server's hostname.  Then 
we allow changes by whomever is responsible for the server.

(We do what we do as a shortcut for our support folk; that way they can 
use two digs to find the host a recalcitrant domain may be running on; 
they don't have to resort to our database.)
