Sure, and that's precisely why I'd want both.  Rapid changes of
REMOTE_HOST associated with the same REMOTE_ADDR would be a pretty
clear sign that something bad is going on.

On the other hand, bad guys typically have access to a bunch of IP
addresses if they need them.  I don't think REMOTE_ADDR is necessarily
all that good a way to identify a miscreant.
