Sorry, I didn't make it clear that "what RFC that is" is "what RFC - if any - says that ephemeral ports should be handed out by default", not "what RFC explains what SHOULD and MUST mean".  *Is* there an RFC that describes well-known, registered, and ephemeral ports?  The first two of them are mentioned in the IANA port number assignment list:

http://www.iana.org/assignments/port-numbers

but that doesn't mention ephemeral ports.
