You cannot delete an IP address range if it is being used by at least one CPE template or CPE device. You need to look up the usage of the IP address range and make sure that it is not being used.
Deleted IP address ranges cannot be restored.
To delete IP address ranges:
By default, the IP pools tab is selected, displaying a table of IP address ranges.
The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, displaying the settings of the IP address range.
The IP address ranges are deleted and are no longer displayed in the table.
