Let the IPv6 regret storm begin ...

We knew the IPv6 transition was going to be tough for technical reasons.

Now we have the first example of IPv6 security problems that will be tough to fix.

Anti-spam software will have a much harder time blocking spam precisely because of IPv6 3.4 x 10^38 addresses.

I'll bet there are a few more IPv6 security problems waiting to be found.

Let's set arbitrary deadlines to switch to IPv6 before we find or fix these problems!

Oh wait, we've already done that.
