More about DHCPv6 stateless mode
Applies To: Windows Server 2008 R2
Windows Server® 2008 supports stateless and stateful DHCPv6 server functionality. DHCPv6 stateless mode clients use DHCPv6 to obtain network configuration parameters other than the IPv6 address, such as DNS server addresses. Clients configure an IPv6 address through a non-DHCPv6 based mechanism such as IPv6 address auto-configuration (based on the IPv6 prefixes included in router advertisements), or static IP address configuration.
In DHCPv6 stateful mode, clients acquire both the IPv6 address as well as other network configuration parameters through DHCPv6.
