Detailed Description

The Set-DnsServerRootHint cmdlet replaces the list of root hints on a Domain Name System (DNS) server. This cmdlet overwrites the list of root hints with the list of root hints that you specify by using the InputObject parameter.

Parameters

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet.

Examples

Example 1: Change the IP address of a root hint

This example adds a root hint to the list of root hints on a DNS server and changes the IP address of the root hint.


 

The first command adds a root hint for the DNS name server that is named H.Root-Servers.net and the IP address 172.24.60.128.


PS C:\> Add-DnsServerRootHint -NameServer "H.Root-Servers.contoso.net" -IPAddress 172.24.60.128

 

The second command assigns the value that is returned by the Get-DnsServerRootHint cmdlet to the variable $a. Get-DnsServerRootHint gets a list of all root hints on the local DNS server. The command then passes that collection to the Where-Object cmdlet by using the pipeline operator. Where-Object filters the resource record to get the root hint for the DNS name server that is named H.Root-Servers.net.


PS C:\> $a = (Get-DnsServerRootHint | Where-Object {$_.NameServer.RecordData.NameServer -eq "H.Root-Servers.contoso.net."} )

 

The third command sets the value of the IP address of the root hint to 172.24.60.132 for the DNS name server H.Root-Servers.net.


PS C:\> $a.IPAddress[0].RecordData.Ipv4address = "172.24.60.132"

 

The fourth command replaces the list of root hints on the local DNS server with the root hint for the DNS name server H.Root-Servers.net.


PS C:\> Set-DnsServerRootHint $a
