Version
9.3.0

Split IPv6 blocks and networks (either from the Unique Local Address Space or the Global Unicast Address Space) into multiple blocks and networks. Divide IPv6 networks into multiple sub-networks to help you better manage your IP space.

One IPv6 block or network can be divided exponentially into 2 blocks or networks, up to a maximum of 1024. Before finalizing the split, Address Manager will show you an overview of all the new blocks or networks that will be created. You will also be able to assign names to each of the new objects.

Note: Users must have change, add, or full access rights on IPv6 objects to split or resize IPv6 blocks.
Limitations
  • A size-1 block or network can't be split.
  • The maximum block size that can be split is /126.
  • A block or network can't be split if the split point falls on a reserved IP address.
  • A block or network can't be split if the split point falls in between a DHCP range.

To split an IPv6 block or network:

  1. Select the IP Space tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
  2. From the configuration drop-down menu, select a configuration.
  3. Click the IPv6 tab. In the IPv6 Blocks section, click the FC00::/6 or the 2003::/3 address space.
  4. Under Address Space, select the block or network that you want to split.
  5. Click the menu beside the block/network name and select Split.
  6. Under Options, select the number of blocks or networks you want to create from the Number of Blocks/Networks drop-down menu.You can divide a block into 2, 4, 8, 16, 32, 64, 128, 256, 512, or 1024 blocks or networks.
  7. Click Continue. The Block/Networks List section opens displaying the number of blocks or networksand their respective IPv6 address ranges.
  8. Under Block/Networks List, enter a unique name for any of the newly create blocks or networks in the Block/Network Name field.
    Note: If you entered a name for the IPv6 block or network when you created or edited it, that name will appear in the Block/Network Name text fields with appended sequential numbers to identify each new block. For example, block/networkname-1, block/networkname-2, block/networkname-3, and so forth. If you did not enter a name for the IPv6 block or network when you created or edited it, the Block/Network Name text fields will be blank for all new blocks or networks.
  9. Click Confirm.
