To remedy these issues, IPv6 was created with unimaginable scale, offering 3.4 × <strong>10</strong> 38 available IP<br />
addresses (enough for every living human to have billions of personal, unique IPv6 addresses). In addition<br />
to offering an immense address range, IPv6 also offers new security features such as IPsec, which<br />
provides security at the packet level. During the transition from IPv4 to IPv6, dual-stack topologies are<br />
being implemented. This allows devices to be configured with both IPv6 and IPv4 addresses.<br />
Modern versions of Windows (beginning with Windows 8) automatically give an IPv6 address priority<br />
over an IPv4 address. Because some applications do not support IPv6, Windows will automatically select<br />
the correct connection for applications, using a method called address sorting.<br />
Windows Server 2012 R2 expands support for IPv6 in Group Policy and allows these new settings to<br />
be used with devices running Windows 8.1 or later. The expanded support includes the following:<br />
■■<br />
■■<br />
■■<br />
TCP/IP printers can be configured to use IPv6 addresses.<br />
In any Group Policy preference, item-level targeting can be used to set an IPv6 address instead<br />
of an IP address range.<br />
For VPN connections, a Use IPv6 check box is available.<br />
