Comment 9 for bug 555210

I agree with Gro-Tsen. I have better IPv6 connectivity than IPv4, and while IPv6 is preferred for most connections, if they are hosted on a 6to4 (2002::/16) host, then IPv4 is used. Some applications can force IPv6 (i.e. ssh -6, or telnet -6), but others cannot (i.e. Firefox or Chromium).

Strange thing is that even though I'm *not* on a 6to4 connection, and even if the *destination* host has 6to4, then IPv4 is preferred. That logic doesn't sound right to me. If *I* had a 6to4 connection as the source IP, then maybe preferring IPv4 to 6to4 would make sense, but not for the destination.
