This chapter describes the management of IPv4 and IPv6 blocks, networks, IP addresses, and IP address discovery and reconciliation.
- IP block—a block is a range of IP space. IP blocks may contain other IP blocks and networks. An IP block must be contained within a configuration or within a parent IP block.
- Network—a network is a group of IP addresses that can be routed. Networks may contain only IP addresses. A network must be contained within an IP block.
- IP address—the actual IP address leased or assigned to a member of a network. An IP address must be contained within a network.
When creating IP address space, you begin by defining IP blocks, then you create networks within those blocks. You can then manage the addresses within the networks.
