Step 6: Upgrading Your DHCP Infrastructure
You can optionally upgrade your routing and DHCP infrastructure to support DHCPv6 for automatic assignment of global or unique local unicast IPv6 addresses or configuration settings for IPv4/IPv6 nodes on your network. By using DHCPv6, an IPv6 host can obtain subnet prefixes and other IPv6 configuration settings. A common use of DHCPv6 is to configure Windows 7-based client computers with the IPv6 addresses of DNS servers on the network. (DNS servers are not configured through IPv6 router discovery.)
The DHCP Server service in Windows Server 2003 does not support stateful address autoconfiguration or the DHCPv6 protocol. The DHCP Server role in Windows Server 2008, however, supports both stateful and stateless IPv6 address autoconfiguration using DHCPv6. The DHCP Client service in Windows 7, Windows Vista, and Windows Server 2008 supports address autoconfiguration using DHCPv6.
Just as with DHCP with IPv4, you also need to deploy and configure DHCPv6 relay agents for each subnet containing Windows 7 clients. Many hardware routers already support a DHCPv6 relay agent. You must configure relay agents with the IPv6 addresses of the DHCPv6 servers on your network. Relay agents can be configured but should not be enabled until you deploy IPv6 routing on your subnets.
When you are ready to enable DHCPv6 on subnets, configure your IPv6 routers to set the Managed Address Configuration and Other Stateful Configuration flags to the appropriate values for stateful or stateless DHCPv6 operation.
