Comment 5 for bug 776040

I talked a bit to Robert because I was concerned about closing user-affecting issues as invalid with no way to progress, just on the grounds that one Canonical team would have to change them rather than another or that we'd have to make a configuration rather than code change.

This bug is closed because the state of ipv6 deployment as of 2011, as we understand it, is that it's just not a reasonable or common case to have a machine that cannot reach ipv4 servers, through either having an an ipv4 route too or having a nat64 gateway at your ISP. If/when that changes (or if it's wrong now) and people are happily using ipv6-only machines, we can reconsider it.
