You should consider the following restrictions when resizing blocks and networks:
  • The new object cannot exceed the address space of its parent object.
  • The resized object must contain some of its previous address space.
  • Resized objects must contain at least three addresses to accommodate the network address, the broadcast address, and one assignable address.
  • If a child object is no longer covered by the range of the resized object, the child object becomes a sibling object to the newly resized object. The child object must be completely covered or uncovered by the newly resized object or an error appears.
  • If an adjacent block is completely covered by a resized block, a confirmation page appears and you need to confirm that you want the adjacent block to become a child of the resized block. The adjacent block must either be entirely covered or not covered by the resized block.
  • Resizing a network that results in abandoned addresses isn't permitted as addresses can't be child objects of a block.
  • Networks cannot be resized to include a sibling object; networks can only be resized to include unallocated space.
Note: If you move an IPv4 block that contains abandoned IPv4 addresses, the abandoned IPv4 addresses will automatically change their state to Static. For more information on abandoned IPv4 addresses, refer to Managing abandoned IPv4 addresses.

To resize, split, or move an IPv4 block:

  1. Select the IPAM tab in the sidebar, then select IPv4 blocks.
    Note: To modify a block within a block, navigate to the parent block by selecting the parent block's range in the IPv4 blocks table, or by selecting the parent block in the IPAM tree view panel. Once you have navigated to the parent block, modify the child block from the parent block's IPv4 blocks and networks table.
  2. Choose one of the following tasks:
    Resize the block
    1. Select the row actions button (⋮) for the block, then select Resize.
    2. Select a resize option and specify the resize values in these fields:
      • CIDR block—select this option to specify the network size using CIDR notation. Type the address and size in the CIDR range field.
      • Range—select this option to specify the network size as a range of IP addresses. Type the starting and ending addresses in the Start address and End address fields.
      • Address and netmask—select this option to specify the network size with an IP address and netmask. Type the IP address and netmask in the Address and Netmask fields.
    3. Select Confirm.
    Split the block
    1. Select the row actions button (⋮) for the block, then select Split.
    2. In the Split point field, enter the IP address at which you want to split the block.
    3. Select Confirm.
    Move the block
    1. Select the row actions button (⋮) for the block, then select Move.
    2. IPv4 Address—type the IP address for the location to which you want to move the block.
    3. Select Confirm.
