Which means the HE figures are conservative, and there are likely to be a whole pile
more people using mechanisms like 6to4 above and beyond the real tunnel figures.
I don't care if its not really a tunnel, and most end-users won't either. I plug it
in, power it up, and 20 seconds later my entire household is IPv6 enabled while I shut
the the cupboard door and move on.
Thats the way IPv6 enablement is *supposed* to be.

Yes, unfortunately Optus doesn't peer locally, so my topologically closest 6to4
gateway (well-known-anycast address 192.88.99.1) is HE, even though PIPE run one locally:

Trace complete.

It would be completely awesome if a few other providers set up 6to4 gateways in-country!

The point is, there is a stack of pent-up demand waiting for the last piece to go into
the jigsaw. Yes, the CPE vendors need to support it, the transit providers need to
route it, the ISPs need to provide it, and the content sites need to advertise it, and
without all of those things it won't happen.

But for those holding back - do you really want to wait until all the other pieces are
in place before you move, so that all the eyeballs are on you when you flick the
switch? Or would you rather get in place early, precisely when nothing much will
happen, and then gradually deal with the issues as they occur before it is supposed to
be in production and supported - and while all the other pieces fall into place, while
the attention is focussed on a bottleneck elsewhere.

if you are the last piece to go into the jigsaw, you'd damn well better fit perfectly
first time, 'cause everyone will be watching you.

Paul.
