create ipv6-block
To add a new block of IPv6 addresses for service access, use the create ipv6-block command. If an address
block with the specified properties already exists, the command will fail.
To add or edit a block of IPv6 addresses, use the enter ipv6-block command. If the specified address block
does not exist, it is created and entered; if the address block exists, it is entered.
You also can use the scope form of this command to enter an existing address block to assign or change
properties.
To delete an existing address block, use the delete form of this command.
create ipv6-block ipv6_address prefix_length {https|snmp|ssh}
delete ipv6-block ipv6_address prefix_length {https|snmp|ssh}
enter ipv6-block ipv6_address prefix_length {https|snmp|ssh}
scope ipv6-block ipv6_address prefix_length {https|snmp|ssh}

Usage Guidelines
Use this command to assign a block of IPv6 addresses to provide access to a specified service (HTTPS, SNMP,
or SSH).
When you create a new IPv6 block, you are automatically entered into ipv6-block mode
(system/services/ipv6-block) with an asterisk indicating the new block assignment is not yet committed.
Up to 25 different blocks can be configured for each service. A address of 0:0:0:0:0:0:0:0 and a prefix of 0
allows unrestricted access to a service. Each block of addresses is identified by its starting IPv6 addresss.
Example
This example shows how to create, enter and verify an IPv6 address block to provide SSH access:
firepower # scope system
firepower /system # scope services
firepower /system/services # create ipv6-block 2001:DB8:1::1 64 ssh
firepower /system/services/ipv6-block* # commit-buffer
firepower /system/services/ipv6-block # up
firepower /system/services # show ipv6-block
