PowerShell Set DNS Settings

Posted on By David Kittell

This only works on Windows 8, 8.1, 10 as the Cmdlets Set-DnsClientServerAddress Get-DnsClientServerAddress are introduced in Windows 8.

First get the interface name(s) you want to modify

Get-DnsClientServerAddress

Change the code below to the interface you wish to change

$primarydns = $args[0]
$secondarydns = $args[1]

Set-DNSClientServerAddress –interfaceAlias Wi-Fi –ServerAddresses ($primarydns,$secondarydns)
Get-DnsClientServerAddress -InterfaceAlias Wi-Fi

.\UpdateDNS.ps1 8.8.8.8 8.8.4.4
