You'll need to go to the Javasoft site (Developer Connection) and
search the database for problems related to reverse domain lookups.
For instance, some wierd things have been done w/ RMI for getting
domain (I assume you want user AND domain).
...
I myself used
String fullUserName = InetAddress.getByName(request.getRemoteAddr()
).getHostName();
because I noticed that getRemoteAddr always works since the address is
right there in the TCP/IP packet.
...
However, the above apis are using InetAddress which in turn
invokes (I believe) the Solaris reverse domain lookup scripts/functions
thru native code. Please refer to documents on JDC or step thru the above
apis in the debugger (JSwat).

Subject: RE: How to obtain user's IP address
The name of the 'user' would be dependent on the machine which called the
servlet. Where did you get request.getRemoteUser()??
There is a getRemoteHost and getRemoteAddr method to the ServletRequest
class which will return either the host or IP-Address of the calling
machine...
public abstract String getRemoteHost()
Returns the fully qualified host name of the agent that sent the request.
Same as the CGI variable REMOTE_HOST.
Never having tried it myself, cannot say if it is reliable under all
browsers or calling contexts....

Subject: How to obtain user's IP address
Hello,
I need to know who visits my web page. In jsp, I got "null" when I used
"request.getRemoteUser()". Then any other mehods can obtain user's name or
IP address?
Thanks
