An IP space acts as a storage for IP addresses that are unique to that particular space. It is a single routing domain with its own IP addresses. All IP addresses must belong to an IP space.

You can manage the IP addresses in an IP space independently of the other. Changes made in one IP space are not reflected in other IP spaces. Since IP spaces are mutually exclusive, the addresses in each IP space can have overlapping address spaces with multiple duplicate IP addresses, without impacting the network integrity.

The IP space for a DHCP host or an HA group is determined by the first subnet or an address range assigned to it. Note that all subsequent assignments must match the first subnet or an address range that is assigned. The application displays an error message if a subnet or an address range with an inconsistent IP space is assigned to a host. To modify an IP space, you must first remove all the assignments and then assign an object from a different space.

Once you create an IP space, you can make copies of it. For more information, see Copying IP Spaces.

To view the list of IP spaces, complete the following:

  1. From the Cloud Services Portal, click Manage -> IPAM/DHCP -> Address Spaces.

  2. BloxOne DDI displays the following information:

    • NAME: The name of the IP space.
    • DESCRIPTION: Additional information about the IP space.
    • UTILIZATION: The percentage of the total IPv4 DHCP utilization of the IP space. This is the percentage of the total number of DHCP hosts, fixed addresses, address ranges, and leases assigned to the IP space versus the total number of IP addresses and all DHCP objects assigned to the IP space. It does not include abandoned addresses or leases.
      • Red: The DHCP resources are 76%-100% utilized.

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

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

You can also perform the following in this tab:

  • Click to reorder the columns.

  • Click  -> Edit or select the check box for the respective record and click the Edit button to modify an IP space.

  • Select an IP space to view additional details. You can view the details like tags, leases, DHCP options, and filters. If you do not want to view the details in the right panel, click .

  • Click to view the IP space utilization details or click to view the details in a tabular format.

  • Enter the value that you want to search in the Search text box. BloxOne DDI displays the list of records matching the keyword in the text box.

  • Click to filter the objects by name and description.

  • Click  -> Move to Recycle Bin to move the object to the recycle bin. You can restore the object later or delete it permanently as required. For more information, see Recycle Bin.
