Comment 112 for bug 417757

I'm sorry, but blacklisting IPv6 is unacceptable. The 'apocalypse' is drawing near — current projections point to 2012 as the most likely date.

So it's almost certain that by 2011 the majority of Internet users will have an IPv6 connection.

And then this begs the question: will Ubuntu 10.04 systems be in production in 2012. Of *course*!

Therefore anybody with the slightest bit of common sense cannot possibly for a moment consider disabling IPv6 out-of-the-box. Having IPv6 work out-of-the-box is extremely important, despite the issues people are having now (which, to be honest, are due to broken IPv6 connectivity or broken DNS resolvers; not Ubuntu's fault, and not something we should fix).
