in reply to I can't find the IP address!

REMOTE_ADDR should contain the IP address. Check out your values by running this. Note that REMOTE_USER will contain the basic authentication username if it is used. (You know those boxes that come up asking for a username and password. If you login, REMOTE_USER will contain the username you logged in as). 

#!/usr/bin/perl -w
use strict;

print "Content-type: text/html\n\n";
print "$_: $ENV{$_}<br />" for keys %ENV;

      Come on now, really.

      print "$_ is $ENV{$_}\n" for sort keys %ENV;

      1 character less, plus it beats the snot out of using map where it is not needed.

        Why not needed? map isn't called in void context; on the other hand the for variant calls print repeatedly, while the other invokes it only once. </nitpick>
