Unless he's directly peering at an exchange into his own datacenter (I doubt it), then he's not hosting it by himself - he's depending on a provider for connectivity and hosting. I don't see what distinction you're trying make between "addressing" and "content". In either case he would be dependent on a third party (that he may have to pay for their services) to keep his site online. He renews his certificate every two years, or his site effectively goes offline. He renews his domain every two years, or his site effectively goes offline. What's the difference supposed to be?
