Add blocks and networks to the IPv6 Unique Local Address space and the Global Unicast Address space.
Unlike the IPv4 space, which is empty until you create blocks and networks, the IPv6
space contains two prefix blocks:
- FC00::/6—prefix for the Unique Local Address space
- 2000::/3—prefix for Global Unicast Address space
These blocks are the starting point for the global and local IPv6 address space. You can't edit, delete, or move these blocks, but you can set deployment options and deployment roles for them.
Note: IPv6 blocks cannot be added at the
configuration level. All IPv6 blocks must be created within the FC00::/6 and
2000::/3 blocks.
