- When the `restrictToUsedIps` flag is set to `true` in the destination parameters:
  - Only **used IP addresses** are synchronized.
  - This prevents the creation of **unused assets** in Rapid7, ensuring a cleaner asset inventory.
    ***Example Scenario***

**In IPAM:**  
A **Fixed IP** is configured with a **MAC address** (i.e., it’s considered a “used” IP).

**In Integration Settings:**  
The `restrictToUsedIps` flag is set to `true`.

**Expected Result in Rapid7:**  
An **asset is created** in Rapid7 corresponding to that IP, and the **MAC address** is also included.

- When the `restrictToUsedIps` flag is set to `false`:
  - **All IPs** in the subnet or address block are synchronized—regardless of usage.
  - This may lead to the creation of **unused assets** in Rapid7.
