| What we are talking about here is setting up default.

Having agreed with half of Alain's mail (and splitting this deliberately
because there are two separate points here), let me disagree with this
part.
What will work best depends upon just what is being counted. If you
count all the possible places I might try to connect, and determine
which address would work, and which would not, you're absolutely right.
But, if you count all the connections I attempt to make, and work out
which address would work, and which would not (or is not best to use)
then you're wrong - because I, and I suspect most people, make huge
numbers of local "connections" compared with the number of remote ones.
(Just to be obvious, sending a DNS request to the local cache is a local
connection for this purpose, and one of those tends to precede each
remote (and many local) connection...)
What's more, there are cases where both will work. For those, which
order we select as the default determines which of the two is used. For
this case (which is for me actually the interesting case - if only
one address works, that's the one that will end up being used) which
order I'd prefer actually depends upon the application. For some,
using the global address is just fine (for some perhaps, even necessary).
For others, it isn't, and the local (more stable, probably) should be
preferred.
