Sometimes you need to test the network connection for a range of IP addresses. Normally I would use ping from a commandline, but it could be a hugh task to test more than 20-30 addresses.
Utilizing a bit of powershell and the test-connection command will help us overcome the task in an easy way:

[code language=”powershell”]1..100 | %{write-host -nonewline "Testing 10.0.0.$_ : "; Test-Connection 10.0.0.$_ -quiet -Count 1}[/code]

The above one-liner will test the connection to all hosts in a range from 10.0.0.1 to 10.0.0.100 and giva a False or True status.
Remember that % is a short way of using the foreach loop, so you could use “foreach” instead of %.
