Comment 1 for bug 776040

This is a fair question but not a code bug with launchpad - launchpad runs behind stock apache servers in the Canonical datacentre; I'm not sure if/when we're going to IP6 enable the datacentre, but when we do LP shouldn't need any changes. As such I'm going to close this.

You should be able to use 6to4 to file bugs; I suggest filing a bug on Ubuntu itself if that isn't working.
