You can combine two or more contiguous IPv6 networks into a shared network. When you do, the DHCP server allocates IP addresses from both subnets. To create a shared network, create the individual subnets, and then create the shared network and add the subnets to it. For more information about shared networks, see *[About](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2202)*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2202)*[Shared](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2202)*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2202)*[Networks](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2202)*.

Adding IPv6 Shared Networks
To add an IPv6 shared network:
1. Select the **Data** **Management** tab.
2. If you have more than one network view in the system, select the network view in which you want to add the network.
3. Select the **DHCP** tab -> **Networks** tab.
4. In the **Shared** **Networks** section, click the **Add** drop-down list and select **Shared Network**-> **IPv6 **or or, click the Add icon drop-down list and select **IPv6 Shared Network**.
5. In the *Add* *IPv6* *Shared* *Network* wizard, do the following:
- **Name**: Enter the name of the shared network.
- **Comment:** Enter information about the shared network.
- **Disabled:** Select this if you want to enable the shared network at a later time. You can disable and enable existing networks instead of removing them from the database. This feature is especially helpful when you have to move or repair the server for a particular network.
6. Click **Next** and do the following to add networks:
1. Click the Add icon.
2. In the *Network* *Selector*, select the networks that you want to include in the shared network. Ensure that the networks are served by the same Grid members to avoid DHCP inconsistencies.
7. Click **Next** to configure DHCP properties described in *[Defining](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35448561/Configuring+DHCPv6+Properties#ConfiguringDHCPv6Properties-bookmark2286)*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35448561/Configuring+DHCPv6+Properties#ConfiguringDHCPv6Properties-bookmark2286)*[General](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35448561/Configuring+DHCPv6+Properties#ConfiguringDHCPv6Properties-bookmark2286)*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35448561/Configuring+DHCPv6+Properties#ConfiguringDHCPv6Properties-bookmark2286)*[IPv6](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35448561/Configuring+DHCPv6+Properties#ConfiguringDHCPv6Properties-bookmark2286)*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35448561/Configuring+DHCPv6+Properties#ConfiguringDHCPv6Properties-bookmark2286)*[Properties](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35448561/Configuring+DHCPv6+Properties#ConfiguringDHCPv6Properties-bookmark2286)*.

Modifying IPv6 Shared Networks
To modify a shared network:
1. From the **Data** **Management** tab, select the **DHCP** tab -> **Networks** tab -> **Shared** **Networks** section ->* shared_network* checkbox, and then click the Edit icon.
2. The *IPv6* *Shared* *Network* editor contains the following tabs from which you can modify data:
- **General**: Modify the fields **Name**, **Comments**, and **Disabled** as described in *[Adding IPv6 Shared Networks](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478013)*.
- **Networks**: Displays the networks that are currently assigned to the shared network. You can add or delete a network. To add a network, click the Add icon. To delete a network, select the *network* checkbox, and then click the Delete icon.
- **IPv6** **DHCP** **Options**: Keep the inherited DHCP properties or override them and enter unique settings for the shared network.

Deleting IPv6 Shared Networks
Though you can delete the networks in a shared network, a shared network must have at least one network in it. To delete a shared network:
1. From the **Data** **Management** tab, select the **DHCP** tab -> **Networks** tab -> **Shared** **Networks** section ->* shared_network* checkbox, and then select **Delete** or **Schedule** **Delete** from the drop-down menu.
2. To delete the shared network now, in the *Delete* *Confirmation* dialog box, click **Yes**. To schedule the deletion, see*[ Scheduling](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35444565/Scheduling+New+IPAM+DHCP+Objects+and+Associated+Port+Configurations#SchedulingNewIPAM/DHCPObjectsandAssociatedPortConfigurations-bookmark145)*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35444565/Scheduling+New+IPAM+DHCP+Objects+and+Associated+Port+Configurations#SchedulingNewIPAM/DHCPObjectsandAssociatedPortConfigurations-bookmark145)*[Deletions](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35444565/Scheduling+New+IPAM+DHCP+Objects+and+Associated+Port+Configurations#SchedulingNewIPAM/DHCPObjectsandAssociatedPortConfigurations-bookmark145)*[.](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35444565/Scheduling+New+IPAM+DHCP+Objects+and+Associated+Port+Configurations#SchedulingNewIPAM/DHCPObjectsandAssociatedPortConfigurations-bookmark145)
The appliance puts the deleted shared network in the Recycle Bin, if enabled.
