*Dual-stack support is an IPv6 transition technology and is a common method for providing clients with both IPv6 and IPv4 Internet connectivity. Dual-stack support indicates that an IPv6-enabled client has been fully tested and verified as able to connect with both IPv6 and IPv4 Microsoft services on the Internet with no perceivable loss of function or performance. Such clients are fully supported by all standard Microsoft support channels, even when the underlying services that enable those experiences remain IPv4 only.
