Comment 28 for bug 24828

Disabling and enabling ipv6 is simple, so, given the current transition situation, we should provide a menu entry and a simple dialog to do this.

Regarding choosing the default behavior, I still am inclined towards ipv4, since if you need ipv6, then your ISP will warn you and you will know this, but if you need ipv4 chances are that you never heard about that. If vista will have a great diffusion, I suppose that ISPs will finally switch to ipv6 so that this will be a suitable default. However, given that vista, suse 10.2 already enable it by default, and who knows about fedora and next OSX release, your mileage may vary on the subject.
