Resize IPv6 blocks and networks in either the Unique Local Address Space or the Global Unicast Address Space to make them larger or smaller.
Note: Users must have change, add, or full access rights on IPv6 objects to split or resize IPv6 blocks.
  • You can't resize a block to a CIDR lower than /126.
  • The maximum allowed network size is /64.
  • The new object can't exceed the address space or be of the same size as its parent block.
  • The resized object must contain some of its previous address space.
  • Blocks and networks can't be resized to non-CIDR boundaries.
  • 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 you will receive an error.
  • If an adjacent block is completely covered by a resized block, a confirmation page opens 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.

To resize an IPv6 block or network:

  1. Select the IPAM tab in the sidebar, then select IPv6 blocks.
  2. Navigate to the parent block that contains the IPv6 block or network by selecting the parent block's range in the IPv6 blocks table, or by selecting the parent block in the IPAM tree view panel.
  3. Select the row actions button (⋮) for the block or network, then select Resize.
  4. Under Address definition, select a resize option and specify the resize values:
    • Prefix size—select this option to specify the block or network size using CIDR notation. Enter the block or network size. For example, 64.
    • Start address and size—select this option to specify the block or network size with the starting IPv6 address. Enter the IPv6 address in the Start address field. For example, 2001:DB8::. In the Size field, enter the size of the block or network using CIDR notation. For example, 64. You don't need to enter a forward slash (/).
  5. Select Confirm.
