Universal DDI uses address blocks to group subnets. An address block is a parent network that can contain other subnets. A leaf network is a network that does not contain other networks. You must associate an address block with an IP space. Once you create an address block, you can make copies of it. For more information, see Copying Address Blocks.

To view the list of address blocks, complete the following:

  1. From the Infoblox Portal, click Configure > Networking > IPAM/DHCP > Address Spaces.

  2. Click on the IP Space to view the list of address blocks that are associated with it.

  3. The application displays the following information:

  • ADDRESS: The IP address and netmask of the subnet.
  • NAME: The name of the address block.
  • DESCRIPTION: Additional information about the address block.
  • UTILIZATION: The percentage of the total IPv4 DHCP utilization of the address block.

    • Red: The DHCP resources are 76%-100% utilized.

    • Orange: The utilization percentage is between 51%-75%.

    • Green: The utilization percentage is between 0%-50%.

  • USAGE: Indicates what the address space is used for, such as IPAM or DHCP or both.
  • COMPARTMENT: The name of the compartment that is associated with this address block. For more information, see Configuring Access Views. This feature is available only for users participating in the Early Access Program (EAP). For information about the EAP, visit Infoblox Early Access Program.

You cannot search for IPv4 Utilization, or First Discovered and Last Discovered fields.

  • Click the filter button, , to filter the objects by name and description. To save a filter after selecting the required parameters click Save Filter, specify a name for the filter, and click Save. To reload a previously saved filter, the saved filters button,  , and select the required filter.
