I can't claim any credit for that diagram; as I said in my previous post, it came from the robtex.com site. I find that site to be quite useful whenever a routing question arises. It also comes in handy with some DNS related questions too. For example, getting a list of all known hostnames used by the same hosting server as the hostname or IP address in question can often provide a clue to the ever popular "Why is [insert ISP here] blocking my [friend's] web site (and/or email)" question.
