Using PowerShell Background Jobs, you can find a large number of online systems within only a few seconds:
function Check-Online {
param(
$computername
)
test-connection -count 1 -ComputerName $computername -TimeToLive 5 -asJob |
Wait-Job |
Receive-Job |
Where-Object { $_.StatusCode -eq 0 } |
Select-Object -ExpandProperty Address
}
$ips = 1..255 | ForEach-Object { "10.10.10.$_" }
$online = Check-Online -computername $ips
$online
This code pings an IP segment from 10.10.10.1 to 10.10.10.255 and returns only those IPs that respond.
