How to Discover DNS Zone by DNS

This task includes the following steps:

Prerequisite - Set up protocol credentials
Discovery is performed by the DNS protocol. To perform discovery, set up the following:
- As all requests are performed from the Probe machine, this machine must be included in the list of servers that can transfer specified zone records. The administrator of the name server grants permissions to transfer the zone from the Probe machine.
- Provide a list of zones that need to be transferred. For details, see DNS Zone by nslookup Job.
Run the discovery
1. Run the Range IPs by ICMP job.
2. Run the TCP ports job.
3. Run the DNS Zone by DNS job.
  
  For details on running jobs, refer to "Module/Job-Based Discovery" in the HPE Universal CMDB Data Flow Management Guide.
