How to force rapid ipv6 adoption

Fri Oct 2 01:37:03 UTC 2015

Either there are multiple translation systems that exist that were invented
late or there are not. Either Owen has never heard of any of them or he is
trolling.

In any case I'm giving up on that conversation. And this whole one. It goes
nowhere.

And this is why v6 is where it is: true believers. Instead of a simple,
practical matter of engineering a transition we got 15 years of advocacy.

It makes the sleazy v4 transfer market look appealing. :)
