Disagree.
The CGI specification (1.1) has the following to say:
* REMOTE_HOST
The hostname making the request. If the server does not have this
information, it should set REMOTE_ADDR and leave this unset.
I would say the equivalent of not setting the REMOTE_HOST CGI variable
is to have request.getRemoteHost() return null.
