Get-DNS Cmdlet
Parameters Output Objects Configuration Settings
The Get-DNS cmdlet is used to query a DNS server for records.
Syntax
Get-DNS [parameters]
Remarks
The cmdlet will attempt to obtain DNS records for the domain specified in Domain for records of the type QueryType. The cmdlet will attempt to use the default DNS settings for the system, but the DNS server and port may be explicitly set as DNSServer and Port.
The cmdlets support pipeline input for some of their parameters. Prebuilding an object and piping it to the cmdlet is very useful, but should be used with caution to prevent security conflicts. Steps have been taken to decrease the risk of a possibly accidental pipe to the cmdlet, for instance, the Credential parameter cannot be piped to the cmdlet and must be specified manually.
