IPv6 Internet support In Windows 8

Most currently implemented networks have the ability to connect to the Internet via IPv4.
However, IPv4 has address limitations that are beginning to show strain and cannot keep up
with the quickly expanding Internet. Currently, network address translation (NAT) is used to
share addresses in residences around the country. This technology allows each home to have
one IP address but multiple devices connected to the Internet. With IPv4 addresses quickly
depleting, NATs may be used on a broader scale, hindering location based services such as
Bing and degrading the P2P application experience.

To remedy these issues, IPv6 was created with unimaginable scale, offering 3x10^38
available IP addresses (enough for every person to have billions to themselves). In addition
to offering an immense address range, IPv6 also offers new security features such as IPsec,
which provides security at the packet level. During the transition from IPv4 to IPv6, dual stack
topologies will be implemented. This allows devices to be configured with both IPv6 and IPv4
addresses. In Windows 8, if an IPv6 address is present, it will automatically take   connection
priority over the IPv4 address. Also, not all applications will support IPv6  immediately.
 Windows will automatically select the correct connection for applications to properly
 communicate by using a method called  address sorting.  These advanced Windows features
indicate that Windows 8 is fully capable of supporting the IPv6 Internet.
