I knew there was a simple answer my aging brain just hadn't figured out. Like I said, I don't grok the OSI model, so I was having problems figuring out why a device without an IP address could accomplish this.
I know enough about networking to look at a diagram (in the day job) and ask "please explain that decision" (us regulators love open-ended questions). Isn't a whelk's chance in a supernova I'll ever get any networking certs.
