You can create range templates to specify an offset and the number of addresses allocated to a range. Note that you cannot create templates for prefix-delegated ranges because the start or end prefix can be outside of the subnet address boundary.  
After you create a DHCP range template, you can configure additional properties such as exclusion ranges and DHCP properties, as described in *<span style="color: #0000ff">[Modifying](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478076)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478076)*<span style="color: #0000ff">[IPv6](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478076)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478076)*<span style="color: #0000ff">[Range](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478076)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478076)*<span style="color: #0000ff">[Templates](https://infoblox-docs.atlassian.net/wiki/spaces/nios85draft/pages/26478076)</span>*. Then when you use the template to create a DHCP range, the range inherits the properties of the template. You can also include a DHCP range template in a network template to automatically create a DHCP range when you use that network template.  
If you have deployed the Cloud Network Automation license on the Grid Master, you can configure range templates for cloud delegation. If you select a default Cloud Platform Appliance for a template, all ranges you create using this template will delegate authority to the same Cloud member. Note that when a Cloud member is removed from the Grid, the delegation will also be removed from the template.

Adding IPv6 Range Templates

To create an IPv6 range template:

1. From the **Data** **Management** tab, select the **DHCP** tab -> **Templates** tab.
2. Click the <span style="color: #000000">drop-down menu of the </span>Add icon and select **IPv6 ****Range** **Template**.
3. In the *Add* *IPv6* *Range* *Template* wizard, complete the following:
  - **Name:** Enter a name that helps identify the IPv6 DHCP range template.
  - **Offset:** An offset in a DHCP range template determines the starting IP address of the range. The appliance adds the offset value you enter here to the start IP address of the network in which you create a DHCP range using this template. That IP address becomes the start IP address of the DHCP range. For example, you specify an offset value of 10 for the 2001:db8:1263:/48 network using the DHCP range template, the appliance creates a range with the start address 2001:db8:1263:0:0:0:0:a.
  - **Number** **of** **Addresses:** Enter the total number of IPv6 addresses to be included in the DHCP range.
  - **Comment:** Optionally, enter additional information about the template.

The **Cloud** section appears when the Cloud Network Automation license is installed on the Grid Master.

Modifying IPv6 Range Templates

You can modify the properties of a DHCP range template and define an exclusion range. For the exclusion range in the template, the start and end addresses are determined by the number of offsets in the DHCP range template's start address and the number of IP addresses in the exclusion range. For more information about exclusion ranges, see *<span style="color: #0000ff">[About](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2204)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2204)*<span style="color: #0000ff">[DHCP](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2204)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2204)*<span style="color: #0000ff">[Ranges](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35979518/Managing+DHCP+Data#ManagingDHCPData-bookmark2204)</span>*.
