I found the Powershell script online to ping a list of IP's and report it's status. This work perfect but I would like to change it from placing the results on the console to writing them to a CSV..

I have tried editing the script to remove write-host and include export-csv but has worked as I was expecting.

$names = Get-Content "c:\devices.txt"
foreach ($name in $names) {
if ( Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue ) {
write-host "$name is up" 
}
else {
write-host "$name is down" 
}
}

Try this:
Get-Content -Path "C:\devices.txt" |
	Select-Object -Property `
		@{Name="Host"; Expression={"Processing $_ ..." | Write-Host; $_}},
		@{Name="Ping"; Expression={Test-Connection -ComputerName $_ -Count 1 -Quiet}} |
	Export-Csv -NoTypeInformation -Path "C:\Temp\test.csv"

Or This
$names = Get-Content "c:\temp\devices.txt"
$Results = @()
foreach ($name in $names) {
if ( Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue ) {
$Answer = "$name is up" 
}
else {
$Answer = "$name is down" 
}
$Results += $Answer 
}
$Results | Export-CSV c:\temp\Results.csv -NoTypeInformation

Nope, that will not work. String arrays cannot be exported that way, you only get the length of each string exported.

A CSV file contains more than one field, for use in a row/column manner. oBdA's usage is correct.

For the message-only version you "export" to a simple text file. But: In PowerShell you refrain from collecting results in vars just to write them out en block later. That can consume a lot of memory unnecessarily.
Get-Content "c:\temp\devices.txt" | %  {
  if (Test-Connection -ComputerName $_ -Count 1 -Quiet)  {
    "$_ is up" 
  } else {
     "$_ is down" 
  }
} | Out-File c:\temp\Results.txt

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.
