Note Well The Internet is (or is intended to be) a network without central intelligence –> a stupid network The Internet is based on the end-to-end principle Every user may reach any other user via the IP address All “services” may be offered anywhere and may be accessed from everywhere This is of course also valid for voice and other communication “services” Voice and other communications do not need a “service” provider at all, they are applications.
