So I was curious as to how many active ip addresses I had on my network and didn’t feel like manually typing “ping <ipaddress>” and wait for it to timeout and then “rinse and repeat”.  Along comes Test-Connection and the –quiet  and –count switches that allow me to make one attempt and then return a True/False status on whether the ip is active or not.

I then decided that this would make a great one liner that would list out the IP address I am testing followed by the True/False status. 

As you can see, it’s a pretty simple one liner that can quickly show you what is active.

1..20 | % {"192.168.1.$($_): $(Test-Connection -count 1 -comp 192.168.1.$($_) -quiet)"}
