module: vmware_host_dns_info
short_description: Gathers info about an ESXi host's DNS configuration information
description:
- This module can be used to gather information about an ESXi host's DNS configuration information when ESXi hostname or Cluster name is given.
- All parameters and VMware object names are case sensitive.
version_added: '2.9'
author:
- Abhijeet Kasurde (@Akasurde)
notes:
- Tested on vSphere 6.5
requirements:
- python >= 2.6
- PyVmomi
options:
cluster_name:
description:
- Name of the cluster from which the ESXi host belong to.
- If C(esxi_hostname) is not given, this parameter is required.
type: str
esxi_hostname:
description:
- ESXi hostname to gather information from.
- If C(cluster_name) is not given, this parameter is required.
