Well, yes and no. "normally" that is AFAIK looked up in /etc/services.  
Which is not a constant in the code, but rather more like hits files.  
Short of a bootstrapping query for ports.iana.org at startup :-)

My point is that we risk running into all kind of wired behavior in  
the future. Take adding AAAA glue. Not all operators are ready for  
deploying it at production quality right now. Imagine we come up with  
something in the future, we then need again wait for updates of  
software to propagate. Take the addition of new RRs or example. TXT  
seems popular...
