Observed IP Ranges at 14:26

Recently I needed to check a whole bunch of servers to see if we had a particular VLAN tagged on any of the ESX Hosts, after a quick post on the VI Toolkit forum and a little messing, the following script tells me quickly which observed IP ranges are on each of the nics in each of the hosts...

Connect-VIServer MYVISERVER
$vmhosts = Get-VMHost | Get-View
foreach ($vmhost in $vmhosts)
{
   $networkSystem = Get-view $vmhost.ConfigManager.NetworkSystem
   Write-Host $vmhost.Name -foregroundcolor yellow
   foreach($netSys in $networkSystem)
   {
       foreach($pnic in $netSys.NetworkConfig.Pnic)
       {
           $subnets = $netSys.QueryNetworkHint($pnic.Device)
           foreach($pnicHint in $subnets)
           {
               Write-Host $pnicHint.Device
               foreach($pnicIpHint in $pnicHint.Subnet)
               {
                   Write-Host "`t" $pnicIpHint.IpSubnet
               }
           }
       }
   }
}
