Powershell script to get FQDN of multple remote computers

We need to create a file for storing all the servers or multiple machines list, I named it as Allservers.txt for and saved it in my local machine c:\temp\Allservers.txt

$allservers = Get-Content -path "c:\temp\allservers.txt"
 
#Looping each server
Foreach($Server in $allservers)
{
$fqdn = Invoke-Command -ComputerName $server -Scriptblock {[System.Net.Dns]::GetHostByName(($server))}
write-host "The FQDN of Server" $server "$fqdn.HostName

}
# End of script

# one can also try this code no difference in ouput
$allservers = Get-Content -path "c:\temp\allservers.txt"
 
#Looping each server
Foreach($Server in $allservers)
{
 Invoke-Command -ComputerName $server -Scriptblock {[System.Net.Dns]::GetHostByName(($env:computerName))}

}
# End of script

One can also retrieve the IP address and FQDN of remote computers, here the code looks like.

# one can also try this code no difference in ouput
$allservers = Get-Content -path "c:\temp\allservers.txt"
 
#Looping each server
Foreach($Server in $allservers)
{
$fqdn = Invoke-Command -ComputerName $server -Scriptblock {[System.Net.Dns]::GetHostByName(($server))}
write-host "The FQDN of Server" $server "$fqdn.HostName
write-host "The FQDN of " $server "Server" $fqdn.HostName "and IP Address" $fqdn.AddressList.IPAddressToString

}
# End of script

One should have admin rights to execute this script on remote computers, generally, system administrators have admin access to computers, if not one will run into permission or access denied issues, make sure you have admin rights on the remote computers.
