 +If [[extensions:teemip-ip-discovery|IP Discovery Datamodel extension]] is installed, versions 3.2.0 and above bring the additional status **Discovered** to the IPObject class and therefore to the IP Addresses. This value may be set by the [[collectors:teemip-ip-discovery-collector|IP Discovery Data collector]] to newly discovered IPs and changed afterwards by the Hostmaster.
