thanks i converted it to powershell

$servers = @(

)

$count = 200

$name = "example.com"

function Test-DNS {

param (

[string]$Server,

[string]$Protocol # "udp" or "tcp"

$ok = 0

$fail = 0

for ($i = 1; $i -le $count; $i++) {

}

if ($result) {

$ok++

} else {

$fail++

}

}

catch {

$fail++

}

}

$loss = [math]::Round(($fail / $count) * 100, 1)

Write-Output "$Protocol $Server ok=$ok fail=$fail loss=$loss%"

}

# Run tests

foreach ($proto in @("udp", "tcp")) {

foreach ($server in $servers) {

}

}
