Not sure if this was discussed before or not, but I am seeing a strange behavior when I try to reach Google.com (and also facebook.com) from a Windows 2008 R2 VM that has dual-stack connectivity, it is taking about 300 seconds to load google.com. Facebook will load faster, but if I log on to it; it wont show my facebook page.
Here is the other strange thing: if I use Internet Explorer with google.comor facebook.com there is no problem whatsoever. If I want to reach IPv6 only pages like [2600::] or IPv4 only pages like cnn.com then there is no problem using either Chrome or IE. So the problem is only with dual-stacked pages when using Chrome. We ran wireshark and found out that the IPv6 address is different for Google.com when using IE or Chrome! I haven't tested yet with Windows7
