Not all systems on a network will reply to a ping test? I know my

That's right. You only have to use a well known internal or external
machine which will answer ping requests, i.e. 8.8.8.8 always
responds to ICMP ping rquests.<br>
You can even check wether the internal connection works by choosing
a well known internal machine. <br>
This way will make you sure that you either have an access to the
intra or extra network or none.<br>
