You are correct with that statement, any network engineer that knows what he is doing should be able to provide this type of documentation upon request.

Another thing to consider is that if you do not have full control of the network, ping may not work for you as it could be blocked between subnets, in my network, if you are not on the admin team, ICMP does not work for you at all, you can see your local subnet, but no more than that.
