You might want to look at [Test-NetConnection](https://docs.microsoft.com/en-us/powershell/module/nettcpip/test-netconnection?view=win10-ps) cmdlet, A combination with Invoke-Command might do the job for you.

Depends on how you have them stored. If you have a list of them in a text file, then Get-Content will work for you.

And you can play with Export-Csv to output the results to a CSV file.

Something like this should get your started:

```
Get-Content -Path C:\Temp\ServersToCheck.txt | Test-NetConnection -Port 3660 | Export-Csv -NoTypeInformation -Path C:\Temp\ServersOutput.csv
```
