Merge two or more contiguous DHCPv4 ranges into a single DHCPv4 block or range when you want to consolidate smaller ranges into a single large range.
The ranges must be contiguous; that is, there can't be any unused or otherwise assigned addresses between the selected ranges. In addition, you must select the block to retain its identity. For example, if each block has a deployment role to a different server, the server selected to retained its identity will retain its role and name.
To merge DHCPv4 ranges:
- From the configuration drop-down menu, select a configuration.
- Select the IP Space tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
- Under IPv4 Blocks, click an IPv4 block.
- Under Blocks and Networks, click an IPv4 network.
- Click the DHCP Ranges tab.
- Under DHCP Ranges, select the check boxes for two or more contiguous DHCP ranges.
- Click Action, and then select Merge Selected.
- Under Selected Siblings, select the item that's to retain its identity after the merge.
- Under Change Control, add comments, if required.
- Click Yes.
