I've never heard of NIC Number or NIC Network Number so I have no idea what they're talking about. In the first instance, perhaps they're referring to the MAC address. In the second instance, perhaps they're referring to the IP address associated with the NIC. These are just guesses, though. I think those are pretty imprecise terms.
Network Boundary probably refers to the classful network boundary. It's the classful major network to which all subnets belong. For example, all IP addresses that start with 10 belong to the 10.0.0.0/8 classful network. They might also be referring to a supernet, which is simply the summary address for multiple more-specific prefixes. Some context would help us decipher the exact meanings.

I am beginning to get confused with some of the terminology used by the different books and was hoping one of you might spare a second to provide a concise definition of the following terms for me: NIC Number NIC Network Number Network Boundary (In terms of summarization at the network boundary) Probably the silliest question you've had on here but my head can't take anymore! Thanks, James.
