Describe the process of updating to DHCPv6 in Windows

Solution

By default IPv6 is enabled on Windows Server 2008 R2. This means that the server already has a link-local IPv6 address.

Link-local addresses are supposed to allow communication on the link, and DHCP is such a local service. However, if we don\'t manually assign a global, site local, or unique local IPv6 address,to the network interface of Windows DHCPv6 server, it cannot assign IPv6 addresses to clients.

To assign an IPv6 address, we need to open the Network and sharing centre on the server:

click “Change adapter settings:

right click the network adapter and launch the properties page.

To install a DHCP server on Windows Server 2008 R2, you have to add the DHCP server role in server manager by right clicking the Roles node.After you select the DHCP server role, a wizard will guide you through the installation process.

Right click the IPv6 node in the DHCP management console and then click “New Scope”. You can change the preference of the scope to 255 to make IP address assignments a bit quicker. If you have multiple DHCPv6 servers, the preference setting tells DHCPv6 clients which server to use.

Whenever a client receives an advertise message of 255, it will immediately proceed with the DHCPv6 message exchange process.

Make sure to select “Obtain IPv6 address automatically, in the IPv6 properties of the client network adapter.

To assign an IPv6 address through DHCPv6, launch an elevated command prompt and run ipconfig/renew6.

This also applies for the release parameter. If you want to release an IPv6 address, you have to type ipconfig/release6. If you want to renew the IPv6 address only for a particular network interface, you have to specify the name of the interface: ipconfig/renew6 “Loacl Area Connectn”.

As with DHCP for IPv4, you can assign additional parameters to Windows clients, such as DNS servers or a domain search list. These parameters can either be added for all scopes on the DHCP server or only for a particular scope.
