How the Internet works:1) If the target IP X is within any of your networks, lookup X's MAC and send the packet to it directly2) If not, find a nexthop device within your network that knows how to reach X. Look up their MAC and send the packet to nexthop.3) Repeat til X gets itStep 2 is done with routing table, that gets updated by various protocols so that cost is involved ( shortest path, highest bandwidth )
