[AusNOG] IPocalypse now (?)

There were at least two proposals for what to do with these.

One to use them as private addresses:
  http://tools.ietf.org/html/draft-wilson-class-e-02

... and another, older one, to make them public:
  http://tools.ietf.org/html/draft-fuller-240space-02

Not sure what happened to these but they are both expired. My personal
preference would be to use them as private addresses, as the pain of
making them safe to use as public addresses is perhaps comparable to
switching to IPv6 anyway :)
