+<para>IPv6 is fully supported and available right from the start with
+Windows Vista and Windows Server 2008.</para>
+
+<para>The previous generation of Windows,
+Windows XP and Windows Server 2003, only support IPv6 on an "experimental"
+basis.  On these Windows versions, the IPv6 TCP/IP stack is not installed
+automatically, rather the system administrator has to install it manually.
+Unless this has already been done on your machine, your machine is not
+IPv6-capable and that's why you see the "Address family not supported"
+error message.</para>
+
+<para>There's also a very experimental IPv6 stack for Windows 2000, and
+Cygwin will try its best to support it, but it's not recommended to install
+it.  Windows NT4 or older never saw IPv6 at all.</para>
+
+<para>For more information about IPv6 on Windows and how to install the
+IPv6 stack, see the <ulink url="http://www.microsoft.com/technet/network/ipv6/ipv6faq.mspx">Microsoft TechNet IPv6 FAQ article</ulink>
