Use PowerShell to Add Multiple IPs to a Network Adapter

Fri, Aug 3, 2012

This script uses WMI to assign a range of IPs to a network adapter.

Function chooseAdapter{
    $adapters = get-wmiobject win32_networkadapterconfiguration -filter "IPEnabled='True'"
    $menu = ""
    $adapters | % {$menu += "["+$_.Index+"]"+$_.Description+"`r`n"}
    $adapterIndex = Read-Host -Prompt ("Choose an adapter by typing the number next to the name of the adapter you'd like to change" + "`r`n" + $menu)
    $chosenAdapter = $adapters | ? {$_.Index -eq $adapterIndex}
    if ($chosenAdapter){
        return $chosenAdapter
    }
    else{
        chooseAdapter
    }
}

Function setStatic($adapter,$ipArray,$subnet){
    $subnetArray = @()
    ForEach ($ip in $ipArray){
        $subnetArray += $subnet
    }
    $adapter.EnableStatic($ipArray, $subnetArray)
    $adapter.SetGateways($adapter.DefaultIPGateway)
    $adapter.SetDNSServerSearchOrder($adapter.DNSServerSearchOrder)
    $adapter.SetDynamicDNSRegistration(“FALSE”)
}

$adapter = chooseAdapter

$subnet = Read-Host -Prompt "Enter the subnet mask"
$first3 = Read-Host -Prompt "Enter the first three octets, ie: 192.168.1"
$ipMin = Read-Host -Prompt "Enter the minimum of the forth octet"
$ipMax = Read-Host -Prompt "Enter the maximum of the forth octet"

$ips = @()
While ($ipMin -lt $ipMax){
    Write-Host Adding $first3 . $ipmin to array
    $ips += ($first3+"."+[string]$ipMin)
    [int]$ipMin += 1
}

setStatic $adapter $ips $subnet
