IP blocks are the main container in the IP address space. You must create at least one IPv4 block in a configuration to be able to add IPv4 networks and IPv4 addresses. IPv4 blocks can contain additional blocks, so you can create a logical structure to group and arrange your IPv4 space.
Note: Address Manager v26.1.0 adds support for creating, retrieving, updating, and
deleting size /31 and /32 IPv4 blocks using the Address Manager GUI, Legacy v1 API, and
RESTful v2 API. Additional operations on /31 and /32 blocks are not supported at this time
(autocreate, find first available, resize, split, merge, move, add parent block, create
partition, templates). Full support for /31 and /32 blocks is planned for inclusion in an
upcoming Address Manager release.
