Add DHCPv6 ranges to configure IPv6 addresses that can be allocated to clients on the network.
DHCP ranges dedicate a portion of a network to DHCP. DHCPv6 ranges must not include
any static addresses that exist on the network and that fall within the DHCP
range.
To add IPv6 DHCP ranges:
- Select the IPAM tab in the sidebar, then select IPv6 blocks.
- Select the 2000::/3 (Global Unicast Address Space) range, or the fc00::/6 (Unique Local Address Space) range.
- Navigate to the IPv6 network that you wish to add a DHCPv6 range to by selecting the network's range in the IPv6 blocks and networks table, or by selecting the network in the IPAM tree view panel.
- Select the IPv6 DHCP ranges tab.
- Select New.
-
Under DHCP range information, set the following parameters:
- Name—enter a descriptive name of the IPv6 DHCP range.
- Size—choose the range of addresses from the drop-down menu or select Customize to define the range of addresses you want to create.
- Create DHCP range using—select from the following
options:
- Auto create—select this check box to automatically create the IPv6 DHCP range.
- Range offset—specify the number of addresses that you want to leave out. For example, if you want to exclude the first 3000 addresses for other uses and create the DHCP range, enter 3000. Address Manager will create the DHCP range defined in the Size field from the 3001st address.
- Range start address—enter a specific IPv6 network address. From this point, Address Manager will create the DHCP range defined in the Size field.
- Under Change control, add comments, if required.
- Select Create or Create and add another.
