[AusNOG] IPocalypse now (?)

[Alastair Johnson]

It was discussed quite a bit in 2007 in the IETF, but the concerns were that it wouldn't give much additional lifetime (18-24 months), and it would be a considerable upgrade to every host on the Internet that you may as well just go to IPv6.

There were also some concerns that it would distract from the deployment of v6.

We're at the end now. 240/4 won't help us, time to move on.

One question I've been asked is why can't they just release the
reserved 240-254 blocks? The registry implies they're reserved for
multicast but I can't find anything concrete on this.  In practice I
suspect that they're hard-coded into so many IP stacks they're
effectively useless anyway.

Cheer,
Steve
