Bug#268631: force preference of IPv4 over IPv6

2009-05-01 Thread Barak A. Pearlmutter
The basic idea is that we want to make sure that either there's no IPv6 at all, or IPv6 works fine. where by fine you actually mean something much stronger: IPv6 at least as good as IPv4 Okay, let's consider people who want IPv6 but (for whatever reason) cannot ensure that their IPv6 is

In the world I live in, my ISP was among the very first here to deploy native IPv6 on DSL *years* ago and is actively seeking IPv6 peering opportunities with as many networks as possible. That is great. Do they artificially slow down IPv4 in order to ensure that IPv6 is faster? IPv6

Yes, let's deploy IPv6, but also make sure that nobody use it! If I understand what you're saying correctly, in essence, you feel sad inside when two IPv6-enabled hosts communicate using IPv4. That is not a technical argument. For the next few years at least, when both are available, IPv4 will
