Powershell: Get IP Address, Subnet, Gateway, DNS servers and MAC address details of remote computer

What are the IP address details of remote computer? When even I came across this question while troubleshooting some problem, I do nothing but logging on to the servers to see the details. Isn’t this a time consuming process? what if I want to get these details using some automation. Unfortunately, there is no windows built-in command like ipconfig /system:mypc1 to get the IP details. So, I decided to make a powershell script which addresses this purpose.

Code

[cmdletbinding()]
param (
 [parameter(ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$true)]
    [string[]]$ComputerName = $env:computername
)

begin {}
process {
 foreach ($Computer in $ComputerName) {
  if(Test-Connection -ComputerName $Computer -Count 1 -ea 0) {
   try {
    $Networks = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName $Computer -EA Stop | ? {$_.IPEnabled}
   } catch {
        Write-Warning "Error occurred while querying $computer."
        Continue
   }
   foreach ($Network in $Networks) {
    $IPAddress  = $Network.IpAddress[0]
    $SubnetMask  = $Network.IPSubnet[0]
    $DefaultGateway = $Network.DefaultIPGateway
    $DNSServers  = $Network.DNSServerSearchOrder
    $WINS1 = $Network.WINSPrimaryServer
    $WINS2 = $Network.WINSSecondaryServer   
    $WINS = @($WINS1,$WINS2)         
    $IsDHCPEnabled = $false
    If($network.DHCPEnabled) {
     $IsDHCPEnabled = $true
    }
    $MACAddress  = $Network.MACAddress
    $OutputObj  = New-Object -Type PSObject
    $OutputObj | Add-Member -MemberType NoteProperty -Name ComputerName -Value $Computer.ToUpper()
    $OutputObj | Add-Member -MemberType NoteProperty -Name IPAddress -Value $IPAddress
    $OutputObj | Add-Member -MemberType NoteProperty -Name SubnetMask -Value $SubnetMask
    $OutputObj | Add-Member -MemberType NoteProperty -Name Gateway -Value ($DefaultGateway -join ",")      
    $OutputObj | Add-Member -MemberType NoteProperty -Name IsDHCPEnabled -Value $IsDHCPEnabled
    $OutputObj | Add-Member -MemberType NoteProperty -Name DNSServers -Value ($DNSServers -join ",")     
    $OutputObj | Add-Member -MemberType NoteProperty -Name WINSServers -Value ($WINS -join ",")        
    $OutputObj | Add-Member -MemberType NoteProperty -Name MACAddress -Value $MACAddress
    $OutputObj
   }
  }
 }
}

end {}

This script is pretty much self explanatory. It uses Win32_NetworkAdapterConfiguration WMI class to get the network configuration details. This script also helps you to get DNS servers, MAC address details, subnetmask and default gateway details. Using this script you can also know the list of network adapters that has DHCP enabled/disabled(means static IPs).

You can save this script to a PS1 fil(say Get-IPDetails.PS1) and run it against list of computers you need. Below is one example.

Hope this helps…
