So, how does one set it from "factory default" to not respond to pings? > But in all cases, what I said above would probably "would probably hold true".

Every browser does this. But when a router responds to a ping then the IP address can be determined and the system at that IP address can then be exploited, if possible. If a router doesn't respond to an ICMP ping then it does not exist. Right?

I know what the router/modem is all about. If you can provide a clear-cut description of what it is you are trying to convince me about then, YES :-) .
