Lorenzo's reply to this statement
Google isn't reachable. There are no IPv6 servers for google.com.
was
Unfortunately, every time we've looked at the data, the
conclusion has been that it would cause unwarranted user
impact. IIRC the most recent blocker was a major US ISP
whose clients would experience breakage if even just one
NS record was dual-stacked. It's not an infrastructure
problem: the servers have supported IPv6 for years, and
some zones like google.fi do have IPv6 NS records.
