You're mistaken, ARPANET is not the internet. ARPANET was one network, there were others. The intenert is the internetworking or network of networks that emerged from connecting those networks together. From the network standpoint it is peer-to-peer as the internet is a network of dumb pipes with intelligence put in the periphery of the network. This is different from say the european minitel network[1] where dumb terminals were connected to a central intelligence.
