How to get an IP address from a server list script

Here’s how you can get the list of IP addresses, FQDN and Ping status with a simple Powershell server list script.

For a start create a servers.txt file in C:\temp folder with the list of servers you would like to resolve. You need to put one server per line. You also need to have Microsoft Excel installed on the system since the result will be exported to .csv file.


servers.txt example:


Now create a new text file and rename it to serverlist.ps1

$counter = 1
$comps = get-content C:\TEMP\servers.txt
$dnsResults = "C:\TEMP\IP address.csv"

function get-dnsres{
foreach ($comp in $comps) {
$TempIP = ([]::GetHostAddresses($comp)) | select IPAddressToString

$status = "Processing system {0} of {1}: {2}" -f $counter,$comps.Count,$comp
Write-Progress 'Resolving DNS' $status -PercentComplete ($counter/$comps.count * 100)
$comp |
select @{Name='ComputerName';Expression={$comp}}, `
@{Name='ResolvesToIP';Expression={[]::GetHostAddresses($comp)}}, `
@{Name='IPResolvesTo';Expression={([]::GetHostEntry($TempIP.IPAddressToString)).HostName}}, `
@{Name='PingStatus'; Expression={ `
if ((get-wmiobject -query "SELECT * FROM Win32_PingStatus WHERE Address='$comp'").statuscode -eq 0) {'Host Online'} `
elseif ((get-wmiobject -query "SELECT * FROM Win32_PingStatus WHERE Address='$comp'").statuscode -eq 11003) {'Destination Host Unreachable'} `
elseif ((get-wmiobject -query "SELECT * FROM Win32_PingStatus WHERE Address='$comp'").statuscode -eq 11010) {'Request Timed Out'} `
elseif ((get-wmiobject -query "SELECT * FROM Win32_PingStatus WHERE Address='$comp'").statuscode -eq $Null) {'NoDNS'}

get-dnsres | export-csv $dnsResults -notypeinformation
invoke-item $dnsResults

Save the script to the same folder at C:\temp.

Before you’ll be able to run the script you will have to enable execution policy on your system:

Start the Powershell in elevated mode (Run as Administrator) and run the following command:

Set-ExecutionPolicy RemoteSigned

Now run the Powershell script by using this command:

powershell -noexit “& “”C:\temp\serverlist.ps1″””

You should get the results on screen and also saved to C:\temp\IP address.csv file.

    This was very helpful. Thank you.
    Just wondering, with the server list text file, is there a way to list IP addresses with their host name and run it in powershell?
