In case Dynamic IP Address scenarios the assets in a customer network are reused and assigned Dynamically.
Based on this scanners like QualysGuard when they capture the Vulnerability and later send it to MetricStream via the connector based integration. The IPV4 Address cannot be the unique key to map it to the right asset on which the Vulnerability was identified.
This needs to be enhanced so that an Unique data like Legacy ID which can be tracked from the Scanner system to MetricStream Asset library or Composite Key which can help retain the mapping correctly though a period where the IPV4 address can get updated.
