Ok, I will not waste my time to argue over obvious things.
You won't get ports more "default" than from this list. Protocols, ports
and service names are registered for a reason.
Ex: If you install MySQL server it will be configured to listen on port
3306\tcp by default on any OS, be it Debian, RHEL, or Windows.
