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.
You can even check wether the internal connection works by choosing a 
well known internal machine.
This way will make you sure that you either have an access to the intra 
or extra network or none.
