$ErrorActionPreference = "silentlycontinue"
for ($i=2; $i -lt 255; $i++)
{
	$IP = "192.168.0.$i"
	Write-Host "Working on $IP .."
 
	if (!(Test-Connection $IP -Count 1))
	{
		Write-Warning "Server is not responding.."
	}
	else
	{
		Write-Host "Server is up and running.."
		$DNS = (Get-WmiObject -ComputerName $IP -Class Win32_NetworkAdapterConfiguration | Where {$_.DNSServerSearchOrder -like "192.168.0.*"})
		if ($DNS)
		{
			Write-Warning "DNS error!"
		}
	}
}

If dns servers are not like 192.168.0, then it will throw error.
