An IP space is a storage for IP addresses that are unique to a particular space. It is a single routing domain with its own IP addresses. All IP addresses must belong to an IP space. You can manage IP addresses in one IP space independently of another; changes made in one IP space are not reflected in other IP spaces. Because IP spaces are mutually exclusive, the addresses in each IP space can have overlapping address spaces with multiple duplicate IP addresses, and this does not affect the network integrity. Once you create an IP space, you can make copies of it.

- Each has its own networks and DNS domains.
- Each has its own private IP spaces in the 10.0.0.0/24 network.
- Each has its own DHCP and DNS servers and uses dynamic DNS updates. The DHCP servers of each corporation serve IP addresses for networks in their respective corporations.
- The DHCP clients in each corporation update DNS zones within their DNS domains.
The two corporations plan to migrate the networks and hosts from the address space Corp 200 to the address space Corp 100 and the corpxyz.com domain. To support both networks in the meantime and to facilitate the migration, you can configure BloxOne DDI to manage the networks and domains of both corporations. As shown in the following diagram, you can configure a host for each corporation and manage their networks independently. Host 1 serves DNS and DHCP to Corp 100. The networks of Corp 100 are contained in the Corp 100 IP space, which is associated with the internal and external DNS views of the corpxyz.com domain. Host 2 serves DNS and DHCP to Corp 200. The networks of Corp 200 are in the Corp 200 IP space, which is associated with both the internal and external DNS views of the corp200.com domain. The two corporations have one overlapping network, 10.1.1.0/24.
