# win_dns_client – Configures DNS lookup on Windows hosts

## Synopsis

- The `win_dns_client` module configures the DNS client on Windows network adapters.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
adapter_names string / required |  | Adapter name or list of adapter names for which to manage DNS settings ('*' is supported as a wildcard value). The adapter name used is the connection caption in the Network Control Panel or via `Get-NetAdapter`, eg `Local Area Connection`.
ipv4_addresses string / required |  | Single or ordered list of DNS server IPv4 addresses to configure for lookup. An empty list will configure the adapter to use the DHCP-assigned values on connections where DHCP is enabled, or disable DNS lookup on statically-configured connections.

## Notes

Note

- When setting an empty list of DNS server addresses on an adapter with DHCP enabled, a change will always be registered, since it is not possible to detect the difference between a DHCP-sourced server value and one that is statically set.

## Examples

    - name: Set a single address on the adapter named Ethernet
      win_dns_client:
        adapter_names: Ethernet
        ipv4_addresses: 192.168.34.5

    - name: Set multiple lookup addresses on all visible adapters (usually physical adapters that are in the Up state), with debug logging to a file
      win_dns_client:
        adapter_names: '*'
        ipv4_addresses:
        - 192.168.34.5
        - 192.168.34.6
        log_path: C:\dns_log.txt

    - name: Configure all adapters whose names begin with Ethernet to use DHCP-assigned DNS values
      win_dns_client:
        adapter_names: 'Ethernet*'
        ipv4_addresses: []
