Get all servers that have ipv6

PowerShell Networking
1

This script allows me to check which servers have ipv6 enabled. I use a module called “SplitPipeline” that does a great job with being able to run multithreaded. This script queried 1500 servers in under 4 mins.

#List the modules we want to load per line
$LoadModules = @'
SplitPipeline
'@.Split("`n").Trim()

ForEach($Module in $LoadModules) 
{
    #Check if Module is Installed
    if($NULL -eq (Get-Module -ListAvailable $Module))
    {
        #Install Module
        Install-Module -Name $Module -Scope CurrentUser -Confirm:$False -Force
        #Import Module
        Import-Module $Module
    }

    #Check if Module is Imported
    if($NULL -eq (Get-Module -Name $Module))
    {
        #Install Module
        Import-Module $Module
    }
}

if($NULL -eq $Servers)
{
    $Servers = ((dsquery * -filter "(&(objectClass=Computer)(objectCategory=Computer)(!(userAccountControl:1.2.840.113556.1.4.803:=2))(operatingSystem=*Server*)(!(servicePrincipalName=*MSClusterVirtualServer*)))" -limit 0) | %{ if ($_ -match '^"CN=(.+?),\s*\w{1,2}=') { $matches[1] } }) | sort -Unique
}

## Used for Progress Bar

$data = @{
    Count = $(($Servers | measure).count)
	Done = 0
}

$Servers | split-pipeline -count 64 -Variable data -ErrorAction SilentlyContinue {
    Process
    {
        Try
        {
            $ipv6Addresses = Invoke-Command -ComputerName $_ -ScriptBlock { Get-NetAdapterBinding -ComponentID ms_tcpip6 -ErrorAction SilentlyContinue }

            #if ($ipv6Addresses.Count -gt 0)
            if ($ipv6Addresses.Enabled -eq "True") 
            {
                $_
            }
        }
        Catch
        {}

        # Count how far along we are
        $done = ++$data.Done

        # show progress
	    Write-Progress -Activity "Done $done" -Status Processing -PercentComplete (100*$done/$data.Count)
    }
