I didn't want to put in an explicit list, because people would interpret
it to be exhaustive. I was trying in the document to establish a
principle, not give a recipe. I don't think this is the place to
attempt to list all the private addresses - especially with IPv6 at such
an early stage with things changing a lot still. 2 is of course a
special case, and I mention some of 3 purely as an example.
