Partitioning divides blocks into multiple, equally sized, smaller blocks or networks. Any remaining space can also be allocated as the same type of object.
To partition an IPv4 block into child blocks or networks:
- Select the IPAM tab in the sidebar, then select IPv4 blocks.
- Navigate to the IPv4 block that you would like to partition by selecting the block's range in the IPv4 blocks table, or by selecting the block in the IPAM tree view panel.
- Select the IPv4 block's object menu (⌄), then select Create partition.
-
Under Allocate space, specify the space to partition and
the type of partitions to create:
- Available space—lists the available unallocated space. Select a block of space from the drop-down menu.
- Set subrange—select this option to specify the space to be partitioned by entering the start and end points of the space.
- Divide into—select Blocks to create IPv4 blocks, or Networks to create IPv4 networks.
- In the Use one of the following methods section,
configure how many blocks or networks are to be created:
- CIDR format—select this option to specify the size and number of items in CIDR notation. Select a value from the drop-down menu.
- Number of blocks/networks—select this option to specify the number of blocks or networks to create. Enter a value in the field.
- Size of block/network—select this option to specify the size of the blocks or networks to create. Enter a value in the field.
- Allocate remaining space—this field appears when creating IPv4 blocks. If your partition settings result in some of the selected space not being allocated, the range of unallocated space is noted here. Select the check box to allocate the remaining range, or deselect the check box to leave the remaining range unallocated.
-
On the Additional details tab, set a name for each
created block/network and apply IPv4 templates if applicable.
- Name—enter a name that will be applied to each new block or network.
- Select a template to apply to each block/network—select a previously created IPv4 template that will be applied to each new block or network.
-
On the Data check tab, review information about the
objects to be created by the partition function.
- When creating IPv4 blocks, the Data check section notes the number of hosts in each block and the number of blocks to be created.
- When creating IPv4 networks, the Data check section notes the number of hosts in each network and the number of networks to be created.
Note: The partition tool creates a maximum of 1024 blocks or networks. If your partition settings create more than 1024 objects, a warning appears in the Data Check section to indicate that the partition operation won't be performed. Adjust your partition settings to reduce the number of objects. - Select Create partition.
