Here is a simple example illustrating how you assign IP address, gateway, and DNS server to a network adapter. The script lists all active network adapters, and when you select one and click OK, uses the hard-coded addresses to assign new values.
Note that the script below only pretends to do the changes. Remove the -WhatIf parameter to actually assign new values:
$NewIP = '192.168.2.12' $NewGateway = '192.168.2.2' $NewDNS = '8.8.8.8' $Prefix = 24 $adapter = Get-NetAdapter | Where-Object Status -eq 'Up' | Out-GridView -Title 'Select Adapter to Configure' -OutputMode Single $index = $adapter.InterfaceIndex New-NetIPAddress -InterfaceIndex $index -IPAddress $NewIP -DefaultGateway $NewGateway -PrefixLength $Prefix -AddressFamily IPv4 -WhatIf Set-DNSClientServerAddress –InterfaceIndex $index –ServerAddresses $NewDNS -whatIf
