Well, they are part of -my- Internet. I'm Bill Manning and I approved this message.
(there, its offical too)

Since you raise the issue of "firewall" - I'll raise you one and ask;

"Are networks behind NAT/ALG or that use RFC 1918 or the v6 equivalent address space,
part of the 'Internet' or are they in networks where access to addresses/service ports
must be explicitly granted?"
