say you want to protect the IP of your visitors and only show the hostname?


  $ip = getenv('REMOTE_HOST');
  $host = @GetHostByAddr($ip);

      $real_host=chop($host);
      if($real_host){
        $host_arr=explode(".", $real_host);
        $count=count($host_arr);
        if($count > 1){
          if(intval($host_arr[$count-1])!=0){
            $host=substr($real_host,0,strrpos($real_host,".")).".*";
          }
          else{
            $host = "*".strstr($real_host, ".");
          }
        }
        else{
          $host=$real_host;
        }
      }
      else{
        $host="";
      }


for me that would put *.dab.bellsouth.net and for AOLers it woud put *.proxy.aol.com
