What Hacker News says?

  1. Regardless of monentary charges (and I'm very aware of them, APNIC is even considering grants to help in IPv6 because it's in limbo for so long), even if we activate IPv6 synchronously there's still many, many problems with it, even when you permanently dual-stack it. One is connectivity. Even theoretically we should have the same network connectivity (so to speak), you can feel the pettiness when Hurricane-Electric…
