        $sth->execute();
        db_rescheck(\$sth,'checknetassigned_get','1');

        if($sth->rows != 1) {
                return(0);

--- new ---
        $sth->execute();
        db_rescheck(\$sth,'checknetassigned_get','1');

        if($sth->rows < 1) {
                return(0);
        }

Would cause strange behafiour in allocations etc because
If a subnet had just had 1 allocatted subnet in it, it would
return as if it had nothing allocated in it.
