For NIOS vDiscovery to work with ESXi and to add DNS names to discovered objects, we need the Cloud Network Automation licence and the NIOS Grid must have the DNS zones added (even if the zones are not assigned to any appliance and even if Infoblox is not actually used for DNS). Otherwise, we just detect if the IP addresses are in use or not. We also need to create the networks in advanced. If we don't, the data doesn't get added.

The current vDiscovery feature supports tenants, networks, and compute VMs only. It does not support data that is retrieved from load balancer networks, load balancer VMs, Kubernetes platform VMs, application gateways, service VMs, SQL VMs, or any other VMs that are created using cloud services such as Kubernetes service or analytics service, where the IPAM is handled by the respective orchestration engines of the cloud provider. Note that if the vDiscovery job retrieves unsupported data from AWS, Azure, or GCP, then it impacts the performance of the vDiscovery process.
