Overlapping IP addresses and hierarchy groups in IPAM

An overlapping IP address occurs when an IP address is assigned to more than one device on a network. This can happen if you have identical subnets in different locations monitored by different DHCP servers on the same network. To avoid IP conflicts when subnets are automatically discovered, you can designate an hierarchy group to which all discovered subnets are assigned when you add a DHCP Server.

If a hierarchy group name is not selected, all discovered subnets for a DHCP Server go to the IP Networks hierarchy group.

IP conflicts are only detected if they occur in the bounds of the same hierarchy group.

Subnets cannot be moved between hierarchy groups.
