Because your IPv4 connection is much more likely to be NATed. This does not matter for HTTP because it plays nice with NATs, but other protocols are much pickier. For these other protocols it would make sense to prefer IPv6.
- nomis80 16y agoSome more details... While IPv6 should be preferred, 6to4 turned out to not work so great in practice. So it's a good decision by Apple to prefer IPv4 over it. But other kinds of IPv6 connectivity (including native) should still be preferred over IPv4.
