Configuring DHCPv6 on Address Manager - BlueCat Integrity - 26.1.0

You need to create and configure an IPv6 network to allocate addresses.

Create an IPv6 network:

1. Select the IPAM tab in the sidebar, then select IPv6 blocks.
2. Select the 2000::/3 (Global Unicast Address Space) range, or the fc00::/6 (Unique Local Address Space) range.
3. To create a network directly within the current block, select New > IPv6 network. To create a network within a sub-block, select the block's range in the IPv6 blocks table, or in the IPAM tree view panel. Once you have navigated to the sub-block, select New > IPv6 network.
4. Under General, set the following parameters:
   • Range—enter the range for the network in CIDR notation.
   • Name—enter a name for the network.
   • Location—select a location from the drop-down menu on which the IP object that you are adding or editing will be based.
5. Under Change control, add comments, if required.
6. Select Create.

Create an IPv6 DHCP range:

7. Select the IPv6 DHCP ranges tab.
8. Select New.
9. 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.
10. Under Change control, add comments, if required.
11. Select Create.

Add a deployment role to the IPv6 network to associate the DHCPv6 range to a DNS/DHCP Server

12. Select the Deployment roles tab.
13. Select New > DHCP deployment role.
14. Under General, set the following parameters:
    • Role—Select the DHCP deployment role type from the drop-down menu.
    • Primary interface—select the primary server interface from the drop-down menu.
    • Secondary interface—select the secondary server interface for failover from the drop-down menu.
15. In the Change control section, add comments if required.
16. Select Create.
    Note: You can also enable Dynamic DNS in order to register DNS for your IPv6 clients. To do this, you will need to enable the ‘Allow Dynamic Updates’ option for the DNS zone you would like to update from the IPv6 network.

    DDNS updates on a Windows client can only be processed through the regular IPv4 DHCP process. When registering DDNS for IPv4, the client will register both an A and AAAA record if both IPv4 and IPv6 are enabled.
