We are looking to find where the IP addresses / ranges are stored in the database. Are they on the probe DB? Or The main uCMDB DB?
The IP ranges are stored in a special discovery configuration file called Domain Scope Document (or DSD for short). Like all other resources, it is stored in the UCMDB (in the DB) and as a file on each of the probes. Please look for DomainScopeDocument.xml under the probe's runtime folder.
