By default IPv6 addresses do not work on Microsoft Windows XP. To make it work on Windows XP, install the interface by executing this command in a console, as an administrator user:
netsh interface ipv6 install
This should not be needed on later versions of Microsoft Windows. Search for
netsh
on
technet.microsoft.com
for more information.
