Description

An address block is an aggregate of IP addresses based on a

power-of-two address space. For example, the 192.168.0.0/16 address

block includes 65536 (2^16) addresses.

Address blocks can be further divided into child address blocks and

subnets. For example, you might want to divide the 192.168.0.0/16

address block further into four child address blocks: 192.168.0.0/17,

192.168.64.0/17, 192.168.128.0/17, and 192.168.192.0/17. A subnet is

used to designate a leaf node of the address space that will not be

further subdivided.

Address blocks are used as a management tool to group and report on

address space usage. The owner and region properties on an address

block or its parent can be used to constrain user access to address

space reports.
