Which means that the DNS port needs to be well-known or fixed in advance. Some other issues to be considered: - this change would make the DNS required for proper Internet operation, whereas it is currently optional (i.e., only for finding the IP address).] - hosts may run services but not have control over their own DNS entry (or SRV records) - firewalling based on ports would no longer be useful (one could argue it should not be, but that's a different issue) >>> Fixed ports do not work behind NAT.

They don't *try* to break things, but then tend to. ;-) As to 'by design', they're not so much trying to break as to 'help' (usually for their own purposes).
