It doesn't really matter, but we commonly refer to the specific
internetwork that has the most routes and greatest content diversity
with a capital 'I".  The rest of them are just internetworks.  I'm
connected to a couple of those...the largest one has 8 ASes and perhaps
50 prefixes.  It's default-free, but no one would confuse it with the
public Internet.  

Since we seem to use capitalization to discriminate the differences,
internetworks like the one I described above are default-free, while
the public Internet has a Default-Free Zone.  Not a good standard,
but people seem to understand this one intuitively.
