CCS VM licensing

Hi,

I need to confirm CCS Vulnerability Manager licensing. I know that CCS VM licensing are usually IP and scan based. I have a query what if a client has license of 1000 nodes and runs scan on 700 servers. After assessing report and information gathering, client deletes those IPs or Site (groups) and add new set of further 700-800 IPs for scanning. Would that work with the license of 1000 endpoints? or it would not by keeping record of scanned IP targets?

Regards.
