The issue is that for the one's you are getting the IP Address for, Reverse DNS zones are not configured properly. About 40-60% of the internet doesn't have properly configured reverse DNS zones.
You can get more information by querying the registrar for that ip block. whois [EMAIL PROTECTED] if arin is not the block registrar, then you have to query the correct one like RIPE or APNIC RIPE is pretty nice in that the server seems to automatically recurse and give good detail. ARIN requires you to single out the sub-net block and perform a whois on it.

Hi all When I call the ServletRequest's getRemoteHost()-method, I get sometimes the fully quialified name and sometimes the IP of the remote host. This is the case also, if the fully qualified name is aviable to the Solaris the server is running on (using nslookup). Now, is there a way to force the Servlet-Engine to deliver the fully qualified name instead of the IP all the times? Thanks for any help.
