Insanity?


Using IPv6 by default can lead to suboptimal results, but there's really no alternative: even in the IETF people think I'm a few bits short of a /128 when I talk about running IPv6-only. And as long as you have both IPv4 and IPv6 connectivity and prefer IPv4, you're never going to see if IPv6 even works, let alone how well.

2. Figure out a PI solution for IPv6 capable of scaling to the
equivalent of hundreds of millions of routes in the core at a
per-route cost two orders of magnitude less than it is today.

Sure:

3. Produce IPv6 NAT.

Believe it or not, there are already products that do IPv6 NAT.
