I'm trying to figure out whether CERNET http://en.wikipedia.org/wiki/CERNET is part of the official Internet, or is behind the Great Firewall where access to invididual networks on the public Internet must be explicitly granted. Anyone in the know?

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?" /bill
