Craig:
Thanks for the helpful information.
getRemoteHost() returns a null value. Not sure what to do to make DNS
available to this server; but, I'll look into it. This may solve much of the
problem.

I intended my question to look for alternatives to getRemoteHost(). We
have a JSP which tracks IP hits.
In many cases, the IP is dynamically assigned from a pool. It appears
these IPs do not have DNS host names. Is there a way to get domain names to
which IP pools are assigned?
