IP Block Management
Managing IP Blocks IP Blocks are edited and managed in either IPAM Manage or the IPAM Gadget.
From either area, you can perform standard block-level actions such as assign, unassign, split, merge, edit attributes, track NAT associations, and more.
These actions are detailed on the IPAM Tab page under Working with IPAM Aggregates. This page will focus primarily on block-level actions and management.
The primary difference differences between the two areas is that are:
- IPAM Manage shows all blocks (or all blocks under an aggregate), regardless of assignment or status
...
- . Some aggregate-level actions are also performed in IPAM Manage, such as setting IPAM alerts and using Aggregate Templates.
- The IPAM Gadget shows only the blocks assigned to the specific resource that you are currently viewing on the Resource Entry Page
...
- ,
...
- but has more advanced assignment options and criteria available (Direct Assign, Smart Assign, Smart Browse).

IPAM Gadget Features
The IPAM Gadget is accessed from the Resource Entry Page → IPAM Gadget, once it has been enabled for the section. Here, you can:
Both IPAM Manage and the IPAM Gadget have customizable column names, order, and visibility, as well as options for user-defined meta columns (for details on setting up customization of the IPAM Manage / IPAM Gadget block list, see IPAM Parameters → Edit Columns). |
Aggregate-Level Actions
Some aggregate-level actions are performed in IPAM Manage, such as setting IPAM alerts and using Aggregate Templates.
These actions are detailed on the IPAM Tab page under Working with IPAM Aggregates. This page will focus primarily on block-level actions and management.

Working in IPAM Manage
In IPAM Manage, you can manage aggregate level actions, such as Split , Clean Up, Alerts, and Export, as well as viewing and managing individual blocks. In IPAM Manage - Advanced, aggregate-level actions are not available.
Open IPAM Manage for a specific Aggregate
Open the IPAM Manage screen for a block or aggregate by:
- Searching for the block in the Global search, and clicking on the resulting CIDR
View the parent aggregate for a Global search / IPAM search result by right clicking to open the action menu for the block, then select "View Parent Aggregate".
- Clicking the "Open" link in the aggregate blocks list from the IPAM tab.
- Clicking on the CIDR header of the Aggregate Block Host Utilization module, or selecting "Manage Aggregate" from the module's Gear Icon from the IPAM tab.
- Clicking on the CIDR displayed in the IPAM Map - Aggregates view.
Open IPAM Manage for all Aggregates/Blocks
Open IPAM Manage for all blocks under all aggregates by clicking the "Advanced" button at the top of the IPAM tab.

- The top level at which an assignment exists denotes the top starting mask of the Netblock Tree View
- Proceeding down the tree, if one of the following conditions are detected, a new branch is created showing all blocks with a prefix at that level - regardless of of whether they exist as editable ProVision block objects.
- A change in assignment is detected (a block is assigned to a different resource than its parent )
- A manual split has been performed at the assignment level of a sibling/cousin block
- If no more changes in assignment are detected down the block tree, the lowest branch will display as containing individual addresses (/32s or /128s). The addresses may be both theoretical and those existing in ProVision.
- Expandable branches display with blue arrows, and denote that the block with that prefix also exists in ProVision → Block View
- Blocks and addresses which exist in ProVision will be editable in Netblock Tree View, but theoretical blocks at any level are not editable unless created in ProVision.

For a simplified example of the how Netblock Tree View displays compared to Block View, we will be using an example aggregate of 19.20.30.0/24 (assigned to 'Available'). The standard Block View for this aggregate shows it has been split to contain a /25, a /26, and two /27s. The /26 and one of the /27s have been assigned to different resources. In Block View, we only see the lowest child blocks that exist in ProVision:
When we switch to Netblock Tree View (by clicking "Netblock Tree") we see only /26s in the top level of the view. This is because 19.20.30.0/26, assigned to '01 Telecom', is the first assigned block encountered. Netblock Tree View will ignore 19.20.30.0/25 and 19.20.30.128/25 because they are assigned to the same resource as 19.20.30.0/24 ('Available').
There are no different assignments under this 19.20.30.0/26. Thus, when you expand it you will see only /32 addresses. As these /32s have not yet been created in ProVision → Block View, they only exist as "theoretical" blocks and are not editable, but aid in viewing the totality of available addresses under that prefix.
If you would like these addresses to be assigned or editable in ProVision, you may split the /26 down to the desired number of /32 addresses using templates or manual splits. This will create the addresses in ProVision and allow those addresses to be edited.
Under those branches display individual /32 addresses, because the /27 is assigned.
However, if 19.20.30.128/25 is split into two /26s in ProVision, the previously theoretical blocks of 19.20.30.128/26 and 19.20.30.194/26 become 'real' objects, and will display as expandable and editable. |
