Re: What are they measuring here?
I think the way both Windows and Linux work, if they auto-configure IPv6 and you try to connect to something that has both IPv4 and IPv6 addresses, it will choose the IPv6 by default.
This often gives a clue as to a problem with the IPv6 configuration somewhere, if there's a long delay and then it connects. This is because your end starts by attempting IPv6 and eventually times out when it doesn't actually work because something's eating packets and falls back to the IPv4.
