"What about "masking" the network?"

That's almost always the case when you are on the internet behind a 'gateway' device like a cable or DSL transceiver(some people call them modems). Your internal network is always hidden from the internet, you can have ports opened up, sending certain kinds of transmissions to internal machines, or a terribly configured endpoint device that allows anything to go anywhere. Still, even in those cases your internal network still isn't visible to others on the internet. Your public(WAN)IP is all anyone will see.

My public IP is masked. Verizon allows that setting. Unless you know the exact name of it and the passkey, it's not visible to the general public.

I just wondered how secure that masking is.
